New functionality has been added to support change marks, indexes, multiple flows, and bookmarks. Existing functionality has been extended in the areas of graphics scaling, "markers" and their retrieval in tables to support e.g. partial sums, and page number referencing. The changes made in this document are intended to meet the requirements for XSL 1.1 described in <a href="#XSL1.1REQ">[XSL 1.1 Requirements]</a>.

defines the Extensible Stylesheet Language (XSL). XSL is a language for expressing stylesheets. Given a class of arbitrarily structured XML <a href="#XML">[XML]</a> or <a href="#XML11">[XML 1.1]</a> documents or data files, designers use an XSL stylesheet to express their intentions about how that structured content should be presented; that is, how the source content should be styled, laid out, and paginated onto some presentation medium, such as a window in a Web browser or a hand-held device, or a set of physical pages in a catalog, report, pamphlet, or book. </p><div class="div2"> <h3><a name="d0e147" id="d0e147"></a>1.1 Processing a Stylesheet</h3><p> An XSL <b>stylesheet processor</b> accepts a document or data in XML and an XSL stylesheet and produces the presentation of that XML source content that was intended by the designer of that stylesheet. There are two aspects of this presentation process: first, constructing a result tree from the XML source tree and second, interpreting the result tree to produce formatted results suitable for presentation on a display, on paper, in speech, or onto other media. The first aspect is called <b>tree transformation</b> and the second is called <b>formatting</b>. The process of formatting is performed by the <b>formatter.</b> This formatter may simply be a rendering engine inside a browser. </p><p> Tree transformation allows the structure of the result tree to be significantly different from the structure of the source tree. For example, one could add a table-of-contents as a filtered selection of an original source document, or one could rearrange source data into a sorted tabular presentation. In constructing the result tree, the tree transformation process also adds the information necessary to format that result tree. </p><p>Formatting is enabled by including formatting semantics in the result tree. Formatting semantics are expressed in terms of a catalog of classes of <b>formatting objects.</b> The nodes of the result tree are formatting objects. The classes of formatting objects denote typographic abstractions such as page, paragraph, table, and so forth. Finer control over the presentation of these abstractions is provided by a set of <b>formatting properties</b>, such as those controlling indents, word- and letter spacing, and widow, orphan, and hyphenation control. In XSL, the classes of formatting objects and formatting properties provide the vocabulary for expressing presentation intent. </p><p> The XSL processing model is intended to be conceptual only. An implementation is not mandated to provide these as separate processes. Furthermore, implementations are free to process the source document in any way that produces the same result as if it were processed using the conceptual XSL processing model. A diagram depicting the detailed conceptual model is shown below.</p><div class="figure"> <p><img src="two-process.gif" alt="The XSL two processes: transformation and formatting"><span class="dlink">   <a href="longdesc/two-process.html" title="Long description of illustration 'The XSL two processes: transformation and formatting'">[D]</a></span></p> <p>XSL Two Processes: Transformation & Formatting</p> </div><div class="div3"> <h4><a name="d0e184" id="d0e184"></a>1.1.1 Tree Transformations</h4><p> Tree transformation constructs the result tree. In XSL, this tree is called the <b>element and attribute tree,</b> with objects primarily in the "formatting object" namespace. In this tree, a formatting object is represented as an XML element, with the properties represented by a set of XML attribute-value pairs. The content of the formatting object is the content of the XML element. Tree transformation is defined in the XSLT Recommendation <a href="#XSLT">[XSLT]</a>. A diagram depicting this conceptual process is shown below.</p><div class="figure"> <p><img src="tree1-2.gif" alt="The XSL Transformation process"><span class="dlink">   <a href="longdesc/tree1-2.html" title="Long description of illustration 'The XSL Transformation process'">[D]</a></span></p> <p>Transform to Another Vocabulary</p> </div><p> The XSL stylesheet is used in tree transformation. A stylesheet contains a set of tree construction rules. The tree construction rules have two parts: a pattern that is matched against elements in the source tree and a template that constructs a portion of the result tree. This allows a stylesheet to be applicable to a wide class of documents that have similar source tree structures. </p><p>In some implementations of XSL/XSLT, the result of tree construction can be output as an XML document. This would allow an XML document which contains formatting objects and formatting properties to be output. This capability is neither necessary for an XSL processor nor is it encouraged. There are, however, cases where this is important, such as a server preparing input for a known client; for example, the way that a WAP (<a href="http://www.wapforum.org/faqs/index.htm">http://www.wapforum.org/faqs/index.htm</a>) server prepares specialized input for a WAP capable hand held device. To preserve accessibility, designers of Web systems should not develop architectures that require (or use) the transmission of documents containing formatting objects and properties unless either the transmitter knows that the client can accept formatting objects and properties or the transmitted document contains a reference to the source document(s) used in the construction of the document with the formatting objects and properties. </p></div><div class="div3"> <h4><a name="d0e209" id="d0e209"></a>1.1.2 Formatting</h4><p> Formatting interprets the result tree in its formatting object tree form to produce the presentation intended by the designer of the stylesheet from which the XML element and attribute tree in the "fo" namespace was constructed. </p><p> The vocabulary of formatting objects supported by XSL - the set of <code>fo:</code> element types - represents the set of typographic abstractions available to the designer. Semantically, each formatting object represents a specification for a part of the pagination, layout, and styling information that will be applied to the content of that formatting object as a result of formatting the whole result tree. Each formatting object class represents a particular kind of formatting behavior. For example, the block formatting object class represents the breaking of the content of a paragraph into lines. Other parts of the specification may come from other formatting objects; for example, the formatting of a paragraph (block formatting object) depends on both the specification of properties on the block formatting object and the specification of the layout structure into which the block is placed by the formatter. </p><p> The properties associated with an instance of a formatting object control the formatting of that object. Some of the properties, for example "color", directly specify the formatted result. Other properties, for example 'space-before', only constrain the set of possible formatted results without specifying any particular formatted result. The formatter may make choices among other possible considerations such as esthetics. </p><p> Formatting consists of the generation of a tree of geometric areas, called the <b>area tree</b>. The geometric areas are positioned on a sequence of one or more pages (a browser typically uses a single page). Each geometric area has a position on the page, a specification of what to display in that area and may have a background, padding, and borders. For example, formatting a single character generates an area sufficiently large enough to hold the glyph that is used to present the character visually and the glyph is what is displayed in this area. These areas may be nested. For example, the glyph may be positioned within a line, within a block, within a page. </p><p> Rendering takes the area tree, the abstract model of the presentation (in terms of pages and their collections of areas), and causes a presentation to appear on the relevant medium, such as a browser window on a computer display screen or sheets of paper. The semantics of rendering are not described in detail in this specification. </p><p> The first step in formatting is to "objectify" the element and attribute tree obtained via an XSLT transformation. Objectifying the tree basically consists of turning the elements in the tree into formatting object nodes and the attributes into property specifications. The result of this step is the <b>formatting object tree</b>. </p><div class="figure"> <p><img src="tree2-3.gif" alt="Objectification of the FO tree"><span class="dlink">   <a href="longdesc/tree2-3.html" title="Long description of illustration 'Objectification of the FO tree'">[D]</a></span></p> <p>Build the XSL Formatting Object Tree</p> </div><p> As part of the step of objectifying, the characters that occur in the result tree are replaced by fo:character nodes. Characters in text nodes which consist solely of white space characters and which are children of elements whose corresponding formatting objects do not permit fo:character nodes as children are ignored. Other characters within elements whose corresponding formatting objects do not permit fo:character nodes as children are errors. </p><p>The content of the fo:instream-foreign-object is not objectified; instead the object representing the fo:instream-foreign-object element points to the appropriate node in the element and attribute tree. Similarly any non-XSL namespace child element of fo:declarations is not objectified; instead the object representing the fo:declarations element points to the appropriate node in the element and attribute tree. </p><p> The second phase in formatting is to refine the formatting object tree to produce the <b>refined formatting object tree</b>. The refinement process handles the mapping from properties to traits. This consists of: (1) shorthand expansion into individual properties, (2) mapping of corresponding properties, (3) determining computed values (may include expression evaluation), (4) handling white-space-treatment and linefeed-treatment property effects, and (5) inheritance. Details on refinement are found in <a href="#refinement"><b>5 Property Refinement / Resolution</b></a>. </p><p>The refinement step is depicted in the diagram below. </p><div class="figure"> <p><img src="tree3-4.gif" alt="Refinement of the FO tree"><span class="dlink">   <a href="longdesc/tree3-4.html" title="Long description of illustration 'Refinement of the FO tree'">[D]</a></span></p> <p>Refine the Formatting Object Tree</p> </div><p> The third step in formatting is the construction of the area tree. The area tree is generated as described in the semantics of each formatting object. The traits applicable to each formatting object class control how the areas are generated. Although every formatting property may be specified on every formatting object, for each formatting object class, only a subset of the formatting properties are used to determine the traits for objects of that class. </p><p>Area generation is depicted in the diagram below. </p><div class="figure"> <p><img src="trees4-5.gif" alt="Area tree generation"><span class="dlink">   <a href="longdesc/trees4-5.html" title="Long description of illustration 'Area tree generation'">[D]</a></span></p> <p>Generate the Area Tree</p> </div><div class="figure"> <p><img src="process-sum.gif" alt="FO-to-area process summary"><span class="dlink">   <a href="longdesc/process-sum.html" title="Long description of illustration 'FO-to-area process summary'">[D]</a></span></p> <p>Summary of the Process</p> </div></div></div><div class="div2"> <h3><a name="d0e284" id="d0e284"></a>1.2 Benefits of XSL</h3><p>Unlike the case of HTML, element names in XML have no intrinsic presentation semantics. Absent a stylesheet, a processor could not possibly know how to render the content of an XML document other than as an undifferentiated string of characters. XSL provides a comprehensive model and a vocabulary for writing such stylesheets using XML syntax. </p><p> This document is intended for implementors of such XSL processors. Although it can be used as a reference manual for writers of XSL stylesheets, it is not tutorial in nature. </p><p> XSL builds on the prior work on Cascading Style Sheets <a href="#CSS2">[CSS2]</a> and the Document Style Semantics and Specification Language <a href="#DSSSL">[DSSSL]</a>. While many of XSL's formatting objects and properties correspond to the common set of properties, this would not be sufficient by itself to accomplish all the goals of XSL. In particular, XSL introduces a model for pagination and layout that extends what is currently available and that can in turn be extended, in a straightforward way, to page structures beyond the simple page models described in this specification. </p><div class="div3"> <h4><a name="d0e297" id="d0e297"></a>1.2.1 Paging and Scrolling</h4><p>Doing both scrollable document windows and pagination introduces new complexities to the styling (and pagination) of XML content. Because pagination introduces arbitrary boundaries (pages or regions on pages) on the content, concepts such as the control of spacing at page, region, and block boundaries become extremely important. There are also concepts related to adjusting the spaces between lines (to adjust the page vertically) and between words and letters (to justify the lines of text). These do not always arise with simple scrollable document windows, such as those found in today's browsers. However, there is a correspondence between a page with multiple regions, such as a body, header, footer, and left and right sidebars, and a Web presentation using "frames". The distribution of content into the regions is basically the same in both cases, and XSL handles both cases in an analogous fashion.</p><p> XSL was developed to give designers control over the features needed when documents are paginated as well as to provide an equivalent "frame" based structure for browsing on the Web. To achieve this control, XSL has extended the set of formatting objects and formatting properties beyond those available in either CSS2 or DSSSL. In addition, the selection of XML source components that can be styled (elements, attributes, text nodes, comments, and processing instructions) is based on XSLT and XPath <a href="#XPATH">[XPath]</a>, thus providing the user with an extremely powerful selection mechanism. </p><p> The design of the formatting objects and properties extensions was first inspired by DSSSL. The actual extensions, however, do not always look like the DSSSL constructs on which they were based. To either conform more closely with the CSS2 specification or to handle cases more simply than in DSSSL, some extensions have diverged from DSSSL. </p><p> There are several ways in which extensions were made. In some cases, it sufficed to add new values, as in the case of those added to reflect a variety of writing-modes, such as top-to-bottom and bottom-to-top, rather than just left-to-right and right-to-left. </p><p> In other cases, common properties that are expressed in CSS2 as one property with multiple simultaneous values, were split into several new properties to provide independent control over independent aspects of the property. For example, the "white-space" property was split into four properties: a "white-space-treatment" property that controls how white space is processed, a "linefeed-treatment" property that controls how line feeds are processed, a "white-space-collapse" property that controls how multiple consecutive spaces are collapsed, and a "wrap-option" property that controls whether lines are automatically wrapped when they encounter a boundary, such as the edge of a column. The effect of splitting a property into two or more (sub-)properties is to make the equivalent existing CSS2 property a "shorthand" for the set of sub-properties it subsumes. </p><p> In still other cases, it was necessary to create new properties. For example, there are a number of new properties that control how hyphenation is done. These include identifying the script and country the text is from as well as such properties as "hyphenation-character" (which varies from script to script). </p><p> Some of the formatting objects and many of the properties in XSL come from the CSS2 specification, ensuring compatibility between the two.</p><p> There are four classes of XSL properties that can be identified as:</p><ol class="enumar"><li><p> CSS properties by copy (unchanged from their CSS2 semantics)</p></li><li><p> CSS properties with extended values</p></li><li><p> CSS properties broken apart and/or extended</p></li><li><p> XSL-only properties</p></li></ol></div><div class="div3"> <h4><a name="d0e331" id="d0e331"></a>1.2.2 Selectors and Tree Construction</h4><p> As mentioned above, XSL uses XSLT and XPath for tree construction and pattern selection, thus providing a high degree of control over how portions of the source content are presented, and what properties are associated with those content portions, even where mixed namespaces are involved. </p><p> For example, the patterns of XPath allow the selection of a portion of a string or the Nth text node in a paragraph. This allows users to have a rule that makes all third paragraphs in procedural steps appear in bold, for instance. In addition, properties can be associated with a content portion based on the numeric value of that content portion or attributes on the containing element. This allows one to have a style rule that makes negative values appear in "red" and positive values appear in "black". Also, text can be generated depending on a particular context in the source tree, or portions of the source tree may be presented multiple times with different styles. </p></div><div class="div3"> <h4><a name="d0e338" id="d0e338"></a>1.2.3 An Extended Page Layout Model</h4><p> There is a set of formatting objects in XSL to describe both the layout structure of a page or "frame" (how big is the body; are there multiple columns; are there headers, footers, or sidebars; how big are these) and the rules by which the XML source content is placed into these "containers". </p><p> The layout structure is defined in terms of one or more instances of a "simple-page-master" formatting object. This formatting object allows one to define independently filled regions for the body (with multiple columns), a header, a footer, and sidebars on a page. These simple-page-masters can be used in page sequences that specify in which order the various simple-page-masters shall be used. The page sequence also specifies how styled content is to fill those pages. This model allows one to specify a sequence of simple-page-masters for a book chapter where the page instances are automatically generated by the formatter or an explicit sequence of pages such as used in a magazine layout. Styled content is assigned to the various regions on a page by associating the name of the region with names attached to styled content in the result tree. </p><p> In addition to these layout formatting objects and properties, there are properties designed to provide the level of control over formatting that is typical of paginated documents. This includes control over hyphenation, and expanding the control over text that is kept with other text in the same line, column, or on the same page. </p></div><div class="div3"> <h4><a name="d0e347" id="d0e347"></a>1.2.4 A Comprehensive Area Model</h4><p> The extension of the properties and formatting objects, particularly in the area on control over the spacing of blocks, lines, and page regions and within lines, necessitated an extension of the CSS2 box formatting model. This extended model is described in <a href="#area_model"><b>4 Area Model</b></a> of this specification. The CSS2 box model is a subset of this model. See the mapping of the CSS2 box model terminology to the XSL Area Model terminology in <a href="#cssbox"><b>7.2 XSL Areas and the CSS Box Model</b></a>. The area model provides a vocabulary for describing the relationships and space-adjustment between letters, words, lines, and blocks.</p></div><div class="div3"> <h4><a name="d0e356" id="d0e356"></a>1.2.5 Internationalization and Writing-Modes</h4><p> There are some scripts, in particular in the Far East, that are typically set with words proceeding from top-to-bottom and lines proceeding either from right-to-left (most common) or from left-to-right. Other directions are also used. Properties expressed in terms of a fixed, absolute frame of reference (using top, bottom, left, and right) and which apply only to a notion of words proceeding from left to right or right to left do not generalize well to text written in those scripts. </p><p> For this reason XSL (and before it DSSSL) uses a relative frame of reference for the formatting object and property descriptions. Just as the CSS2 frame of reference has four directions (top, bottom, left and right), so does the XSL relative frame of reference have four directions (before, after, start, and end), but these are relative to the "writing-mode". The "writing-mode" property is a way of controlling the directions needed by a formatter to correctly place glyphs, words, lines, blocks, etc. on the page or screen. The "writing-mode" expresses the basic directions noted above. There are writing-modes for "left-to-right - top-to-bottom" (denoted as "lr-tb"), "right-to-left - top-to-bottom" (denoted as "rl-tb"), "top-to-bottom - right-to-left" (denoted as "tb-rl") and more. See <a href="#writing-mode"><b>7.29.7 writing-mode</b></a> for the description of the "writing-mode" property. Typically, the writing-mode value specifies two directions: the first is the inline-progression-direction which determines the direction in which words will be placed and the second is the block-progression-direction which determines the direction in which blocks (and lines) are placed one after another. In addition, the inline-progression-direction for a sequence of characters may be implicitly determined using bidirectional character types for those characters from the Unicode Character Database <a href="#UNICODE-CD">[UNICODE Character Database]</a> for those characters and the Unicode bidirectional (BIDI) algorithm <a href="#UNICODE-TR9">[UNICODE UAX #9]</a>. </p><p> Besides the directions that are explicit in the name of the value of the "writing-mode" property, the writing-mode determines other directions needed by the formatter, such as the shift-direction (used for subscripts and superscripts), etc. </p></div><div class="div3"> <h4><a name="d0e371" id="d0e371"></a>1.2.6 Linking</h4><p> Because XML, unlike HTML, has no built-in semantics, there is no built-in notion of a hypertext link. In this context, "link" refers to "hypertext link" as defined in <a href="https://www.w3.org/TR/html401/struct/links.html#h-12.1">http://www.w3.org/TR/html401/struct/links.html#h-12.1</a> as well as some of the aspects of "link" as defined in <a href="https://www.w3.org/TR/xlink/#intro">http://www.w3.org/TR/xlink/#intro</a>, where "link is a relationship between two or more resources or portions of resources, made explicit by an XLink linking element". Therefore, XSL has a formatting object that expresses the dual semantics of formatting the content of the link reference and the semantics of following the link.</p><p> XSL provides a few mechanisms for changing the presentation of a link target that is being visited. One of these mechanisms permits indicating the link target as such; another allows for control over the placement of the link target in the viewing area; still another permits some degree of control over the way the link target is displayed in relationship to the originating link anchor.</p><p>XSL also provides a general mechanism for changing the way elements are formatted depending on their active state. This is particularly useful in relation to links, to indicate whether a given link reference has already been visited, or to apply a given style depending on whether the mouse, for instance, is hovering over the link reference or not.</p></div></div></div><div class="div1"> <h2><a name="d0e386" id="d0e386"></a>2 XSL Transformation</h2><div class="div2"> <h3><a name="d0e389" id="d0e389"></a>2.1 Tree Construction</h3><p>The Tree Construction is described in "XSL Transformations" <a href="#XSLT">[XSLT]</a>.

Because the data model is the same whether the original document was XML 1.0 or XML 1.1, the semantics of XSLT processing do not depend on the version of XML used by the original document.

This process comprises several steps, some of which depend on others in a non-sequential way. Our model for formatting will be the construction of an <b>area tree</b>, which is an ordered tree containing geometric information for the placement of every glyph, shape, and image in the document, together with information embodying spacing constraints and other rendering information; this information is referred to under the rubric of <em>traits</em>, which are to areas what properties are to formatting objects and attributes are to XML elements. <a href="#area_model"><b>4 Area Model</b></a> will describe the area tree and define the default placement constraints on stacked areas. However, this is an abstract model which need not be actually implemented in this way in a formatter, so long as the resulting tangible form obeys the implied constraints. Constraints might conflict to the point where it is impossible to satisfy them all. In that case, it is implementation-defined which constraints should be relaxed and in what order to satisfy the others. </p><p><em>Formatting objects</em> are elements in the formatting object tree, whose names are from the XSL namespace; a formatting object belongs to a <em>class</em> of formatting objects identified by its element name. The formatting behavior of each class of formatting objects is described in terms of what areas are created by a formatting object of that class, how the traits of the areas are established, and how the areas are structured hierarchically with respect to areas created by other formatting objects. <a href="#fo-section"><b>6 Formatting Objects</b></a> and <a href="#pr-section"><b>7 Formatting Properties</b></a> describe formatting objects and their properties.</p><p>Some formatting objects are <em>block-level</em> and others are <em>inline-level</em>. This refers to the types of areas which they generate, which in turn refer to their default placement method. Inline-areas (for example, glyph-areas) are collected into lines and the direction in which they are stacked is the inline-progression-direction. Lines are a type of block-area and these are stacked in a direction perpendicular to the inline-progression-direction, called the block-progression-direction. See <a href="#area_model"><b>4 Area Model</b></a> for detailed decriptions of these area types and directions.</p><p>In Western writing systems, the block-progression-direction is "top-to-bottom" and the inline-progression-direction is "left-to-right". This specification treats other writing systems as well and introduces the terms "block" and "inline" instead of using absolute indicators like "vertical" and "horizontal". Similarly this specification tries to give relatively-specified directions ("before" and "after" in the block-progression-direction, "start" and "end" in the inline-progression-direction) where appropriate, either in addition to or in place of absolutely-specified directions such as "top", "bottom", "left", and "right". These are interpreted according to the value of the writing-mode property.</p><p>Central to this model of formatting is <em>refinement</em>. This is a computational process which finalizes the specification of properties based on the attribute values in the XML result tree. Though the XML result tree and the formatting object tree have very similar structure, it is helpful to think of them as separate conceptual entities. Refinement involves</p><ul><li><p>propagating the various inherited values of properties (both implicitly and those with an attribute value of "inherit"), </p></li><li><p>evaluating expressions in property value specifications into actual values, which are then used to determine the value of the properties,</p></li><li><p>converting relative numerics to absolute numerics,</p></li><li><p>constructing some composite properties from more than one attribute</p></li></ul><p>Some of these operations (particularly evaluating expressions) depend on knowledge of the area tree. Thus refinement is not necessarily a straightforward, sequential procedure, but may involve look-ahead, back-tracking, or control-splicing with other processes in the formatter. Refinement is described more fully in <a href="#refinement"><b>5 Property Refinement / Resolution</b></a>.</p><p>To summarize, formatting proceeds by constructing an area tree (containing areas and their traits) which satisfies constraints based on information contained in the XML result tree (containing element nodes and their attributes). Conceptually, there are intermediate steps of constructing a formatting object tree (containing formatting objects and their properties) and refinement; these steps may proceed in an interleaved fashion during the construction of the area tree.</p><div class="div2"> <h3><a name="d0e506" id="d0e506"></a>3.1 Conceptual Procedure</h3><p>This subsection contains a conceptual description of how formatting could work. This conceptual procedure does not mandate any particular algorithms or data structures as long as the result obeys the implied constraints.</p><p>The procedure works by processing formatting objects. Each object, while being processed, may initiate processing of other objects. While the objects are hierarchically structured, the processing is not; processing of a given object is rather like a co-routine which may pass control to other processes, but pick up again later where it left off. The procedure starts by initiating the processing of the fo:root formatting object.</p><p>Unless otherwise specified, processing a formatting object creates areas and returns them to its parent to be placed in the area tree. Like a co-routine, when given control, it initiates, then continues formatting of its own children (if any), or some subset of them. The formatting object supplies parameters to its children based on the traits of areas already in the area tree, possibly including areas generated by the formatting object or its ancestors. It then disposes of the areas returned by its formatting object children. It might simply return such an area to its parent (and will always do this if it does not generate areas itself), or alternatively it might arrange the area in the area tree according to the semantics of the formatting object; this may involve changing its geometric position. It terminates processing when all its children have terminated processing (if initiated) and it is finished generating areas.</p><p>Some formatting objects do not themselves generate areas; instead these formatting objects simply return the areas returned to them by their children. Alternatively, a formatting object may continue to generate (and return) areas based on information discovered while formatting its own children; for example, the fo:page-sequence formatting object will continue generating pages as long as it contains a flow with unprocessed descendants.</p><p>Areas returned to an fo:root formatting object are page-viewport-areas, and are simply placed as children of the area tree root in the order in which they are returned, with no geometrical implications.</p><p>As a general rule, the order of the area tree parallels the order of the formatting object tree. That is, if one formatting object precedes another in the depth-first traversal of the formatting object tree, with neither containing the other, then all the areas generated by the first will precede all the areas generated by the second in the depth-first traversal of the area tree, unless otherwise specified. Typical exceptions to this rule would be things like side floats, before floats, and footnotes.</p><p>At the end of the procedure, the areas and their traits have been constructed, and they are required to satisfy constraints described in the definitions of their associated formatting objects, and in the area model section. In particular, size and position of the areas will be subject to the placement and spacing constraints described in the area model, unless the formatting object definition indicates otherwise.</p><p>The formatting object definitions, property descriptions, and area model are not algorithms. Thus, the formatting object semantics do not specify how the line-breaking algorithm must work in collecting characters into words, positioning words within lines, shifting lines within a container, etc. Rather this specification assumes that the formatter has done these things and describes the constraints which the result is supposed to satisfy. Thus, the constraints do not specify at what time an implementation makes use of that information; the constraints only specify what must be true after processing has been completed. An actual implementation may well make use of some constraints at a time other than when formatting the formatting object for which the constraint applies. For example, the constraint given by the "hyphenate" property on an fo:character would typically be used during line-building, rather than when progessing the fo:character. Other examples include constraints for keeps and breaks.</p></div></div><div class="div1"> <h2><a name="area_model" id="area_model"></a>4 Area Model</h2><p>In XSL, one creates a tree of formatting objects that serve as inputs or specifications to a formatter. The formatter generates a hierarchical arrangement of areas which comprise the formatted result. This section defines the general model of these areas and how they interact. The purpose is to present an abstract framework which is used in describing the semantics of formatting objects. It should be seen as describing a series of constraints for conforming implementations, and not as prescribing particular algorithms.</p><div class="div2"> <h3><a name="area-intro" id="area-intro"></a>4.1 Introduction</h3><p>The formatter generates an ordered tree, the <b>area tree,</b> which describes a geometric structuring of the output medium. The terms <b>child, sibling, parent, descendant,</b> and <b>ancestor</b> refer to this tree structure. The tree has a <b>root node</b>.</p><p>Each area tree node other than the root is called an <b>area</b> and is associated to a rectangular portion of the output medium. Areas are not formatting objects; rather, a formatting object generates zero or more rectangular areas, and normally each area is generated by a unique object in the formatting object tree.</p><div class="note"><p class="prefix"><b>Note:</b></p><p>The only exceptions to this rule are when several leaf nodes of the formatting object tree are combined to generate a single area, for example when several characters in sequence generate a single ligature glyph. In all such cases, relevant properties such as <b>font-family</b> and <b>font-size</b> must be the same for all the generating formatting objects (see section <a href="#area-linebuild"><b>4.7.2 Line-building</b></a>).</p></div><p>An area has a <b>content-rectangle</b>, the portion in which its child areas are assigned, and optional <b>padding</b> and <b>border</b>. The diagram shows how these portions are related to one another.

Individual traits are used either for rendering the area or for defining constraints on the result of formatting, or both. Traits used strictly for formatting purposes or for defining constraints may be called <b>formatting traits</b>, and traits used for rendering may be called <b>rendering traits</b>. Traits whose values are copied or derived from a property of the same or a corresponding name are listed in <a href="#property-index"><b>B Property Summary</b></a> and <a href="#refinement"><b>5 Property Refinement / Resolution</b></a>; other traits are listed below.</p><div class="note"><p class="prefix"><b>Note:</b></p><p>Traits are also associated with FOs during the process of refinement. Some traits are assigned during formatting, while others are already present after refinement.</p></div><p>The semantics of each type of formatting object that generates areas are given in terms of which areas it generates and their place in the area-tree hierarchy. This may be further modified by interactions between the various types of formatting objects. The properties of the formatting object determine what areas are generated and how the formatting object's content is distributed among them. (For example, a word that is not to be hyphenated may not have its glyphs distributed into areas on two separate line-areas.)</p><p>The traits of an area are either:</p><p><b>directly-derived</b>: the values of directly-derived traits are the computed value of a property of the same or a corresponding name on the generating formatting object, or</p><p><b>indirectly-derived</b>: the values of indirectly-derived traits are the result of a computation involving the computed values of one or more properties on the generating formatting object, other traits on this area or other interacting areas (ancestors, parent, siblings, and/or children) and/or one or more values constructed by the formatter. The calculation formula may depend on the type of the formatting object.</p><p>This description assumes that refined values have been computed for all properties of formatting objects in the result tree, i.e., all relative and corresponding values have been computed and the inheritable values have been propagated as described in <a href="#refinement"><b>5 Property Refinement / Resolution</b></a>. This allows the process of inheritance to be described once and avoids a need to repeat information on computing values in this description.</p><p>The indirectly-derived traits are: <b>block-progression-direction</b>, <b>inline-progression-direction</b>, <b>shift-direction</b>, <b>glyph-orientation</b>, <b>is-reference-area</b>, <b>is-viewport-area</b>, <b>left-position</b>, <b>right-position</b>, <b>top-position</b>, <b>bottom-position</b>, <b>left-offset</b>, <b>top-offset</b>, <b>is-first</b>, <b>is-last</b>, <b>alignment-point</b>, <b>area-class</b>, <b>start-intrusion-adjustment</b>, <b>end-intrusion-adjustment</b>, <b>generated-by</b>, <b>returned-by</b>, <b>folio-number</b>, <b>blink</b>, <b>underline-score</b>, <b>overline-score</b>, <b>through-score</b>, <b>underline-score-color</b>, <b>overline-score-color</b>, <b>through-score-color</b>, <b>alignment-baseline</b>, <b>baseline-shift</b>, <b>nominal-font</b>, <b>dominant-baseline-identifier</b>, <b>actual-baseline-table</b>, and <b>script</b>. </p></div><div class="div2"> <h3><a name="area-rect" id="area-rect"></a>4.2 Rectangular Areas</h3><div class="div3"> <h4><a name="d0e723" id="d0e723"></a>4.2.1 Area Types</h4><p>There are two types of areas: <b>block-areas</b> and <b>inline-areas</b>. These differ according to how they are typically stacked by the formatter. An area can have block-area children or inline-area children as determined by the generating formatting object, but a given area's children must all be of one type. Although block-areas and inline-areas are typically stacked, some areas can be explicitly positioned.</p><p>A <b>line-area</b> is a special kind of block-area whose children are all inline-areas. A <b>glyph-area</b> is a special kind of inline-area which has no child areas, and has a single glyph image as its content.</p><p>Typical examples of areas are: a paragraph rendered by using an fo:block formatting object, which generates block-areas, and a character rendered by using an fo:character formatting object, which generates an inline-area (in fact, a glyph-area).</p></div><div class="div3"> <h4><a name="area-common" id="area-common"></a>4.2.2 Common Traits</h4><p>Associated with any area are two directions, which are derived from the generating formatting object's <b>writing-mode</b> and <b>reference-orientation</b> properties: the <b>block-progression-direction</b> is the direction for stacking block-area descendants of the area, and the <b>inline-progression-direction</b> is the direction for stacking inline-area descendants of the area. Another trait, the <b>shift-direction</b>, is present on inline-areas and refers to the direction in which baseline shifts are applied. Also the <b>glyph-orientation</b> defines the orientation of glyph-images in the rendered result.</p><p>If the reference-orientation for an area is 0, then the top, bottom, left, and right edges of the content are parallel to those of the area's parent and consistent with them. Otherwise the edges are rotated from those of the area's parent as described in <a href="#reference-orientation"><b>7.21.3 reference-orientation</b></a>. The inline-progression-direction and block-progression-direction are determined by the location of these edges as described in <a href="#writing-mode"><b>7.29.7 writing-mode</b></a>.</p><p>The Boolean trait <b>is-reference-area</b> determines whether or not an area establishes a coordinate system for specifying indents. An area for which this trait is <code>true</code> is called a <b>reference-area</b>. Only a reference-area may have a block-progression-direction which is different from that of its parent. A reference-area may be either a block-area or an inline-area. Only specific formatting objects generate reference areas.</p><p>The Boolean trait <b>is-viewport-area</b> determines whether or not an area establishes an opening through which its descendant areas can be viewed, and can be used to present clipped or scrolled material; for example, in printing applications where bleed and trim is desired. An area for which this trait is <code>true</code> is called a <b>viewport-area</b>. A viewport-area also has the value <code>true</code> for the <b>is-reference-area</b> trait.</p><p>A common construct is a <b>viewport/reference pair</b>. This is a viewport-area <var>V</var> and a block-area reference-area <var>R</var>, where <var>R</var> is the sole child of <var>V</var> and where the start-edge and end-edge of the content-rectangle of <var>R</var> are parallel to the start-edge and end-edge of the content-rectangle of <var>V</var>.</p><p>Each area has the traits <b>top-position</b>, <b>bottom-position</b>, <b>left-position</b>, and <b>right-position</b> which represent the distance from the edges of its content-rectangle to the like-named edges of the nearest ancestor reference-area (or the page-viewport-area in the case of areas generated by descendants of formatting objects whose absolute-position is <code>fixed</code>); the <b>left-offset</b> and <b>top-offset</b> determine the amount by which a relatively-positioned area is shifted for rendering. These traits receive their values during the formatting process, or in the case of absolutely positioned areas, during refinement.</p><p>The <b>block-progression-dimension</b> and <b>inline-progression-dimension</b> of an area represent the extent of the content-rectangle of that area in each of the two relative directions.</p><p>Other traits include:</p><ul><li><p>the <b>is-first</b> and <b>is-last</b> traits, which are Boolean traits indicating the order in which areas are generated and returned (See <a href="#define-returned-by"><b>6.1.1 Definitions Common to Many Formatting Objects</b></a>) by a given formatting object. <b>is-first</b> is <code>true</code> for the first area (or only area) generated and returned by a formatting object, and <b>is-last</b> is <code>true</code> for the last area (or only area);</p></li><li><p>the amount of space outside the border-rectangle: <b>space-before</b>, <b>space-after</b>, <b>space-start</b>, and <b>space-end</b> (though some of these may be required to be zero on certain classes of area);</p><div class="note"><p class="prefix"><b>Note:</b></p><p>"Before", "after", "start", and "end" refer to relative directions and are defined below.</p></div></li><li><p>the thickness of each of the four sides of the padding: <b>padding-before</b>, <b>padding-after</b>, <b>padding-start</b>, and <b>padding-end</b>;</p></li><li><p>the style, thickness, and color of each of the four sides of the border: <b>border-before</b>, etc.;</p></li><li><p>the background rendering of the area: <b>background-color</b>, <b>background-image</b>, and other background traits; and</p></li><li><p>the <b>nominal-font</b> for an area, as determined by the font properties and the character descendants of the area's generating formatting object.

The appropriate class for a given condition is referred to as a <b>context</b> and an area in this class is a <b>context-area</b>. As defined in Section <a href="#pag-intro"><b>6.4.1 Introduction</b></a>, <b>page-reference-areas</b> are areas generated by an fo:page-sequence using the specifications in an fo:page-master, and <b>column-areas</b> are normal-flow-reference-areas generated from a region-body, or region-reference-areas generated from other types of region-master.</p><p>A keep or break condition is an open statement about a formatting object and the tree relationships of the areas it generates with the relevant context-areas. These tree relationships are defined mainly in terms of <b>leading</b> or <b>trailing</b> areas. If <var>A</var> is a descendant of <var>P</var>, then <var>A</var> is defined to be <b>leading</b> in <var>P</var> if <var>A</var> has no preceding sibling which is a normal area, nor does any of its ancestor areas up to but not including <var>P</var>. Similarly, <var>A</var> is defined to be <b>trailing</b> in <var>P</var> if <var>A</var> has no following sibling which is a normal area, nor does any of its ancestor areas up to but not including <var>P</var>. For any given formatting object, the <b>next</b> formatting object in the flow is the first formatting object following (in the pre-order traversal order) which is not a descendant of the given formatting object and which generates and returns normal areas.</p><p>Break conditions are either break-before or break-after conditions. A break-before condition is <b>satisfied</b> if the first area generated and returned by the formatting object is leading within a context-area. A break-after condition depends on the next formatting object in the flow; the condition is satisfied if either there is no such next formatting object, or if the first normal area generated and returned by that formatting object is leading in a context-area.</p><p>Break conditions are imposed by the <b>break-before</b> and <b>break-after</b> properties. A refined value of <code>page</code> for these traits imposes a break condition with a context consisting of the page-reference-areas; a value of <code>even-page</code> or <code>odd-page</code> imposes a break condition with a context of even-numbered page-reference-areas or odd-numbered page-reference-areas, respectively; a value of <code>column</code> imposes a break condition with a context of column-areas. A value of <code>auto</code> in a break-before or break-after trait imposes no break condition.</p><p>Keep conditions are either keep-with-previous, keep-with-next, or keep-together conditions. A keep-with-previous condition on an object is satisfied if the first area generated and returned by the formatting object is not leading within a context-area, or if there are no preceding areas in a post-order traversal of the area tree. A keep-with-next condition is satisfied if the last area generated and returned by the formatting object is not trailing within a context-area, or if there are no following areas in a pre-order traversal of the area tree. A keep-together condition is satisfied if all areas generated and returned by the formatting object are descendants of a single context-area.</p><p>Keep conditions are imposed by the "within-page", "within-column", and "within-line" components of the "keep-with-previous", "keep-with-next", and "keep-together" properties. The refined value of each component specifies the <b>strength</b> of the keep condition imposed, with higher numbers being stronger than lower numbers and the value <code>always</code> being stronger than all numeric values. A component with value <code>auto</code> does not impose a keep condition. A "within-page" component imposes a keep-condition with context consisting of the page-reference-areas; "within-column", with context consisting of the column-areas; and "within-line" with context consisting of the line-areas.</p><p>The area tree is constrained to satisfy all break conditions imposed. Each keep condition must also be satisfied, except when this would cause a break condition or a stronger keep condition to fail to be satisfied. If not all of a set of keep conditions of equal strength can be satisfied, then some maximal satisfiable subset of conditions of that strength must be satisfied (together with all break conditions and maximal subsets of stronger keep conditions, if any).</p></div><div class="div2"> <h3><a name="rendmodel" id="rendmodel"></a>4.9 Rendering Model</h3><p> This section makes explicit the relationship between the area tree and visually rendered output. </p><p> Areas generate three types of marks: (1) the area background, if any, (2) the marks intrinsic to the area (a glyph, image, or decoration) if any, and (3) the area border, if any. </p><p> An area tree is rendered by causing marks to appear on an output medium in accordance with the areas in the area tree.

For example, an fo:character object generates a glyph-area, and this is rendered by drawing a glyph within that area's content-rectangle in accordance with the area's font traits and <b>glyph-orientation</b> and <b>blink</b> traits. </p><p> In addition, other traits (for example the various score and score-color traits) specify other intrinsic marks. In the case of score traits (<b>underline-score</b>, <b>overline-score</b> and <b>through-score</b>), the score thickness and position are specified by the nominal-font in effect; where the font fails to specify these quantities, they are implementation-dependent. </p></div><div class="div3"> <h4><a name="rend-layer" id="rend-layer"></a>4.9.6 Layering and Conflict of Marks</h4><p> Marks are layered as described below, which defines a partial ordering of which marks are <b>beneath</b> which other marks. </p><p> Two marks are defined to <b>conflict</b> if they apply to the same point in the output medium. When two marks conflict, the one which is beneath the other does not affect points in the output medium where they both apply. </p><p> Marks generated by the same area are layered as follows: the area background is beneath the area's intrinsic marks, and the intrinsic marks are beneath the border. Layering among the area's intrinsic marks is defined by the semantics of the area's generating formatting object and its properties. For example, a glyph-area's glyph drawing comes beneath the marks generated for text-decoration. </p><p>The stacking layer of an area is defined by its stacking context and its z-index value. The stacking layer of an area <var>A</var> is defined to be less than that of an area <var>B</var> if some ancestor-or-self <var>A'</var> of <var>A</var> and <var>B'</var> of <var>B</var> have the same stacking context and the z-index of <var>A'</var> is less than the z-index of <var>B'</var>. If neither stacking layer is less than the other then they are defined to have the same stacking layer.</p><p>If <var>A</var> and <var>B</var> are areas, and the stacking layer of <var>A</var> is less than the stacking layer of <var>B</var>, then all marks generated by <var>A</var> are beneath all marks generated by <var>B</var>. </p><p> If <var>A</var> and <var>B</var> are areas with the same stacking layer, the backgrounds of <var>A</var> and <var>B</var> come beneath all other marks generated by <var>A</var> and <var>B</var>. Further, if <var>A</var> is an ancestor of <var>B</var> (still with the same stacking layer), then the background of <var>A</var> is beneath all the areas of <var>B</var>, and all the areas of <var>B</var> are beneath the intrinsic areas (and border) of <var>A</var>. </p><p> If <var>A</var> and <var>B</var> have the same stacking layer and neither is an ancestor of the other, then it is an error if either their backgrounds conflict or if a non-background mark of <var>A</var> conflicts with a non-background mark of <var>B</var>.

For any property that has not been specified on the object the inherited (see <a href="#inheritance"><b>5.1.4 Inheritance</b></a>) or initial value, as applicable, is used as the effective value.

Three variants of the property value are distinguished: the specified value, the computed value, and the actual value. The "specified value" is one that is placed on the formatting object during the tree-construction process. A specified value may not be in a form that is directly usable; for example, it may be a percentage or other expression that must be converted into an absolute value. A value resulting from such a conversion is called the "computed value". Finally, the computed value may not be realizable on the output medium and may need to be adjusted prior to use in rendering. For example, a line width may be adjusted to become an integral number of output medium pixels. This adjusted value is the "actual value."</p><div class="div3"> <h4><a name="d0e4194" id="d0e4194"></a>5.1.1 Specified Values</h4><p>The specified value of a property is determined using the following mechanisms (in order of precedence):</p><ol class="enumar"><li><p> If the tree-construction process placed the property on the formatting object, use the value of that property as the specified value. This is called "explicit specification".</p></li><li><p> Otherwise, if the property is inheritable, use the value of that property from the parent formatting object, generally the computed value (see below).</p></li><li><p> Otherwise use the property's initial value, if it has one. The initial value of each property is indicated in the property's definition. If there is no initial value, that property is not specified on the formatting object. In general, this is an error. </p></li></ol><p>Since it has no parent, the root of the result tree cannot use values from a parent formatting object; in this case, the initial value is used if necessary.</p></div><div class="div3"> <h4><a name="d0e4211" id="d0e4211"></a>5.1.2 Computed Values</h4><p>Specified values may be absolute (i.e., they are not specified relative to another value, as in "red" or "2mm") or relative (i.e., they are specified relative to another value, as in "auto", "2em", and "12%"), or they may be expressions. For most absolute values, no computation is needed to find the computed value. Relative values, on the other hand, must be transformed into computed values: percentages must be multiplied by a reference value (each property defines which value that is), values with a relative unit (em) must be made absolute by multiplying with the appropriate font size, "auto" values must be computed by the formulas given with each property, certain property values ("smaller", "bolder") must be replaced according to their definitions. The computed value of any property that controls a border width where the style of the border is "none" is forced to be "0pt".</p><p> Some properties have more than one way in which the property value can be specified. The simplest example of such properties are those which can be specified either in terms of a direction relative to the writing-mode (e.g., padding-before) or a direction in terms of the absolute geometric orientation of the viewport (e.g., padding-top). These two properties are called the relative property and the absolute property, respectively. Collectively, they are called "corresponding properties".</p><p>Specifying a value for one property determines both a computed value for the specified property and a computed value for the corresponding property. Which relative property corresponds to which absolute property depends on the writing-mode. For example, if the "writing-mode" at the top level of a document is "lr-tb", then "padding-start" corresponds to "padding-left", but if the "writing-mode" is "rl-tb", then "padding-start" corresponds to "padding-right". The exact specification of how to compute the values of corresponding properties is given in <a href="#compcorr"><b>5.3 Computing the Values of Corresponding Properties</b></a>.</p><p>In most cases, elements inherit computed values. However, there are some properties whose specified value may be inherited (e.g., some values for the "line-height" property). In the cases where child elements do not inherit the computed value, this is described in the property definition.</p></div><div class="div3"> <h4><a name="d0e4224" id="d0e4224"></a>5.1.3 Actual Values</h4><p>A computed value is in principle ready to be used, but a user agent may not be able to make use of the value in a given environment. For example, a user agent may only be able to render borders with integer pixel widths and may, therefore, have to adjust the computed width to an integral number of media pixels. The actual value is the computed value after any such adjustments have been applied.</p></div><div class="div3"> <h4><a name="inheritance" id="inheritance"></a>5.1.4 Inheritance</h4><p>Some of the properties applicable to formatting objects are "inheritable." Such properties are so identified in the property description. The inheritable properties can be placed on any formatting object. The inheritable properties are propagated down the formatting object tree from a parent to each child. (These properties are given their initial value at the root of the result tree.) For a given inheritable property, if that property is present on a child, then that value of the property is used for that child (and its descendants until explicitly re-set in a lower descendant); otherwise, the specified value of that property on the child is the computed value of that property on the parent formatting object. Hence there is always a specified value defined for every inheritable property for every formatting object.</p></div></div><div class="div2"> <h3><a name="shortexpan" id="shortexpan"></a>5.2 Shorthand Expansion</h3><p>In XSL there are two kinds of shorthand properties; those originating from CSS, such as "border", and those that arise from breaking apart and/or combining CSS properties, such as "page-break-inside".

The <b>selection criteria</b> are the following font properties: "font-family", "font-style", "font-variant", "font-weight", "font-stretch", and "font-size", plus, for some formatting objects, one or more characters. The details of how the selection criteria are used is specified in the "font-selection-strategy" property (see <a href="#font-selection-strategy"><b>7.9.3 font-selection-strategy</b></a>). </p><p> The <b>nominal-font</b> trait is set to the selected font.

The value of this property is a compound value with three components: a baseline-identifier for the dominant-baseline, a baseline-table and a baseline-table font-size. The <b>dominant-baseline-identifier</b> is set from the first component. The baseline-table font-size is used to scale the the positions of the baselines from the baseline table and, then, the position of the dominant-baseline is subtracted from the positions of the other baselines to yield a table of offsets from the dominant baseline.

In some documents, in particular those written with the Arabic or Hebrew script, and in some mixed-language contexts, text in a single (visually displayed) block may appear with mixed directionality. This phenomenon is called bidirectionality, or "BIDI" for short. </p><p>The Unicode BIDI algorithm <a href="#UNICODE-TR9">[UNICODE UAX #9]</a> defines a complex algorithm for determining the proper directionality of text. The algorithm is based on both an implicit part based on character properties, as well as explicit controls for embeddings and overrides. </p><p>The final step of refinement uses this algorithm and the Unicode bidirectional character type of each character to convert the implicit directionality of the text into explicit markup in terms of formatting objects. For example, a sub-sequence of Arabic characters in an otherwise English paragraph would cause the creation of an inline formatting object with the Arabic characters as its content, with a "direction" property of "rtl" and a "unicode-bidi" property of "bidi-override". The formatting object makes explicit the previously implicit right to left positioning of the Arabic characters. </p><p>As defined in <a href="#UNICODE-TR9">[UNICODE UAX #9]</a>, the Unicode BIDI algorithm takes a stream of text as input, and proceeds in three main phases: </p><ol class="enumar"><li><p>Separation of the input text into paragraphs. The rest of the algorithm affects only the text between paragraph separators. </p></li><li><p>Resolution of the embedding levels of the text. In this phase, the bidirectional character types, plus the Unicode directional formatting codes, are used to produce <b>resolved embedding levels</b>. The normative bidirectional character type for each character is specified in the Unicode Character Database <a href="#UNICODE-CD">[UNICODE Character Database]</a>. </p></li><li><p>Reordering the text for display on a line-by-line basis using the resolved embedding levels, once the text has been broken into lines. </p></li></ol><p>The algorithm, as described above, requires some adaptions to fit into the XSL processing model. First, the final, text reordering step is not done during refinement. Instead, the XSL equivalent of re-ordering is done during area tree generation. The <b>inline-progression-direction</b> of each glyph is used to control the stacking of glyphs as described in <a href="#area-stackcon"><b>4.2.5 Stacking Constraints</b></a>. The <b>inline-progression-direction</b> is determined at the block level by the "writing-mode" property and within the inline formatting objects within a block by the "direction" and "unicode-bidi" properties that were either specified on inline formatting objects generated by tree construction or are on inline formatting objects introduced by this step of refinement (details below). </p><p>Second, the algorithm is applied to a sequence of characters coming from the content of one or more formatting objects. The sequence of characters is created by processing a fragment of the formatting object tree. A <b>fragment</b> is any contiguous sequence of children of some formatting object in the tree. The sequence is created by doing a pre-order traversal of the fragment down to the fo:character level. During the pre-order traversal, every fo:character formatting object adds a character to the sequence. Furthermore, whenever the pre-order scan encounters a node with a "unicode-bidi" property with a value of "embed" or "bidi-override", add a Unicode RLO/LRO or RLE/LRE character to the sequence as appropriate to the value of the "direction" and "unicode-bidi" properties. On returning to that node after traversing its content, add a Unicode PDF character. In this way, the formatting object tree fragment is flattened into a sequence of characters. This sequence of characters is called the <b>flattened sequence of characters</b> below. </p><p>Third, in XSL the algorithm is applied to <b>delimited text ranges</b> instead of just paragraphs. A delimited text range is a maximal flattened sequence of characters that does not contain any delimiters. Any formatting object that generates block-areas is a delimiter. It acts as a delimiter for its content. It also acts as a delimiter for its parent's content. That is, if the parent has character content, then its children formatting objects that generate block-areas act to break that character content into <b>anonymous blocks</b> each of which is a delimited text range. In a similar manner, the fo:multi-case formatting object acts as delimiter for its content and the content of its parent. Finally, text with an orientation that is not perpendicular to the dominant-baseline acts as a delimiter to text with an orientation perpendicular to the dominant-baseline. We say that <b>text has an orientation perpendicular to the dominant-baseline</b> if the glyphs that correspond to the characters in the text are all oriented perpendicular to the dominant-baseline. </p><div class="note"><p class="prefix"><b>Note:</b></p><p>In most cases, a delimited text range is the maximal sequence of characters that would be formatted into a sequence of one or more line-areas. For the fo:multi-case and the text with an orientation perpendicular to the dominant-baseline, the delimited range may be a sub-sequence of a line or sequence of lines. For example, in Japanese formatted in a vertical writing-mode, rotated Latin and Arabic text would be delimited by the vertical Japanese characters that immediately surround the Latin and Arabic text. Any formatting objects that generated inline-areas would have no affect on the determination of the delimited text range. </p></div><p>For each delimited text range, the <b>inline-progression-direction</b> of the nearest ancestor (including self) formatting object that generates a block-area determines the <b>paragraph embedding level</b> used in the Unicode BIDI algorithm. This is the default embedding level for the delimited text range. </p><p><b>Embedding levels</b> are numbers that indicate how deeply the text is nested, and the default direction of text on that level. The minimum embedding level of text is zero, and the maximum embedding level is level 61. Having more than 61 embedding levels is an error. An XSL processor may signal the error. If it does not signal the error, it must recover by allowing a higher maximum number of embedding levels. </p><p>The second step of the Unicode BIDI algorithm labels each character in the delimited text range with a <b>resolved embedding level</b>. The resolved embedding level of each character will be greater than or equal to the paragraph embedding level. Right-to-left text will always end up with an odd level, and left-to-right and numeric text will always end up with an even level. In addition, numeric text will always end up with a higher level than the paragraph level. </p><p>Once the resolved embedding levels are determined for the delimited text range, new fo:bidi-override formatting objects with appropriate values for the "direction" and "unicode-bidi" properties are inserted into the formatting object tree fragment that was flattened into the delimited text range such that the following constraints are satisfied: </p><ol class="enumar"><li><p>For any character in the delimited text range, the <b>inline-progression-direction</b> of the character must match its resolved embedding level. </p></li><li><p>For each resolved embedding level <var>L</var> from the paragraph embedding level to the maximum resolved embedding level, and for each maximal contiguous sequence of characters <var>S</var> for which the resolved embedding level of each character is greater than or equal to <var>L</var>, </p><ol class="enumla"><li><p>There is an inline formatting object <var>F</var> which has as its content the formatting object tree fragment that flattens to <var>S</var> and has a "direction" property consistent with the resolved embedding level <var>L</var>. </p><div class="note"><p class="prefix"><b>Note:</b></p><p><var>F</var> need not be an inserted formatting object if the constraint is met by an existing formatting object or by specifying values for the "direction" and "unicode-bidi" properties on an existing formatting object. </p></div></li><li><p>All formatting objects that contain any part of the sequence <var>S</var> are properly nested in <var>F</var> and retain the nesting relationships they had in the formatting object tree prior to the insertion of the new formatting objects. </p><div class="note"><p class="prefix"><b>Note:</b></p><p>Satisfying this constraint may require splitting one or more existing formatting objects in the formatting object tree each into a pair of formatting objects each of which has the same set of computed property values as the original, unsplit formatting object.

The created pairs must continue to nest properly to satisfy this constraint. For example, assume Left-to-right text is represented by the character "L" and Right-to-left text is represented by "R". In the sub-tree </p><pre> <fo:block> LL <fo:inline id="A" color="red">LLLRRR</fo:inline> RR </fo:block> </pre><p> assuming a paragraph embedding level of "0", the resolved embedding levels would require the following (inserted and replicated) structure: </p><pre> <fo:block> LL <fo:inline id="A" color="red">LLL</fo:inline> <fo:bidi-override direction="rtl"> <fo:inline color="red">RRR</fo:inline> RR </fo:bidi-override> </fo:block> </pre><p> Note that the fo:inline with id equal to "A" has been split into two fo:inlines, with only the first one retaining the original id of "A".

That is, add to the refined formatting object tree only as many fo:bidi-override formatting objects, beyond the formatting objects created during tree construction, as are needed to represent the embedding levels present in the document. </p></li></ol></div><div class="div2"> <h3><a name="d0e5032" id="d0e5032"></a>5.9 Expressions</h3><p>All property value specifications in attributes within an XSL stylesheet can be expressions.

When an absolute length is written without a unit, the unit power is assumed to be zero. Hence, all floating point numbers are a length with a power of zero.</p><p> Each unit name has associated with it an internal ratio to some common internal unit of measure (e.g., a meter). When a value is written in a property expression, it is first converted to the internal unit of measure and then mathematical operations are performed.</p><p>In addition, only the mod, addition, and subtraction operators require that the numerics on either side of the operation be absolute numerics of the same unit power. For other operations, the unit powers may be different and the result should be mathematically consistent as with the handling of powers in algebra.</p><p>A property definition may constrain an absolute length to a particular power. For example, when specifying font-size, the value is expected to be of power "one". That is, it is expected to have a single powered unit specified (e.g., 10pt).</p><p>When the final value of a property is calculated, the resulting power of the absolute numeric must be either zero or one.

When converting to an absolute numeric, the percentage is defined in the property definition as being a percentage of some known property value. If the percentage evaluates to "auto" the complete expression evaluates to "auto". </p><p> For example, a value of "110%" on a "font-size" property would be evaluated to mean 1.1 times the current font size.

There is a single simple-page-master, named "all-pages". This page-master has two regions defined upon it, "xsl-region-body" and "xsl-region-before". The region named "xsl-region-before" is a page header that accepts static-content (said content is omitted for simplicity in this example). The region named "xsl-region-body" is assigned the content of the single fo:flow in the single fo:page-sequence.</p><p>In this example, the definition of "xsl-region-body" has a "writing-mode" property.

Since no "writing-mode" property is specified on either the fo:root nor its child, the fo:page-sequence, the initial value would be used for the writing mode for the content that fills the region reference area.

Thus for the xsl-region-body the specification on the region definition for "xsl-region-body" would be used and the content would receive vertical formatting instead of the default horizontal formatting. Similarly for the xsl-region-before, the computed value of the "writing-mode" on the region definition would be used, in this case the initial value of "lr-tb" inherited from fo:root and the content of the xsl-region-before would be formatted horizontally. </p></div><p><em>object</em> <b>from-table-column</b>(<var>NCName</var>?)</p><p>The <code>from-table-column</code> function returns the inherited value of the property whose name matches the argument specified, or if omitted for the property for which the expression is being evaluated, from the fo:table-column whose column-number matches the column for which this expression is evaluated and whose number-columns-spanned also matches any span.

Formatting is the process which converts the description into a presentation. See <a href="#fo-jc-intro"><b>3 Introduction to Formatting</b></a>. The presentation is represented, abstractly, by an area tree, as defined in the area model. See <a href="#area_model"><b>4 Area Model</b></a>. Each possible presentation is represented by one or more area trees in which the information in the refined formatting object tree is positioned on a two and one-half dimensional surface.</p><p> There are three kinds of formatting objects: (1) those that generate areas, (2) those that return areas, but do not generate them, and (3) those that are used in the generation of areas. The first and second kinds are typically called <b>flow objects</b>. The third kind is either a <b>layout object</b> or an <b>auxiliary object</b>. The kind of formatting object is indicated by the terminology used with the object. Formatting objects of the first kind are said to "generate one or more areas". Formatting objects of the second kind are said to "return one or more areas". Formatting objects of the first kind may both generate and return areas. Formatting objects of the third kind are "used in the generation of areas"; that is, they act like parameters to the generation process. </p><div class="div3"> <h4><a name="define-returned-by" id="define-returned-by"></a>6.1.1 Definitions Common to Many Formatting Objects</h4><p> This categorization leads to defining two traits which characterize the relationship between an area and the formatting objects which generate and return that area. These traits are <b>generated-by</b> and <b>returned-by</b>. </p><p> The value of the <b>generated-by</b> trait is a single formatting object. A formatting object <var>F</var> is defined to <b>generate</b> an area <var>A</var> if the semantics of <var>F</var> specify the generation of one or more areas and <var>A</var> is one of the areas thus generated, or is a substituted form of one of the areas thus generated, as specified in section <a href="#area-linebuild"><b>4.7.2 Line-building</b></a>.</p><p>In the case of substituted glyph-areas, the generating formatting object is deemed to be the formatting object which generated the glyph-area which comes first in the sequence of substituted glyph-areas. In the case of an inserted glyph-area (e.g., an automatically-generated hyphen) the generating formatting object is deemed to be the generating formatting object of the last glyph-area preceding the inserted glyph-area in the pre-order traversal of the area tree. </p><p> The value of the <b>returned-by</b> trait is a set of pairs, where each pair consists of a formatting object and a positive integer. The integer represents the position of the area in the ordering of all areas returned by the formatting object. </p><p> A formatting object <var>F</var> is defined to <b>return the sequence of areas</b> <var>A</var>, <var>B</var>, <var>C</var>, ... if the pair (<var>F</var>,1) is a member of the <b>returned-by</b> trait of <var>A</var>, the pair (<var>F</var>,2) is a member of the <b>returned-by</b> trait of <var>B</var>, the pair (<var>F</var>,3) is a member of the <b>returned-by</b> trait of <var>C</var>, ... </p><p> If an area is a member of the sequence of areas returned by a formatting object, then either it was generated by the formatting object or it was a member of the sequence of areas returned by a child of that formatting object. Not all areas returned by a child of a formatting object need be returned by that formatting object. A formatting object may generate an area that has, as some of its children areas, areas returned by the children of that formatting object. These children (in the area tree) of the generated area are not returned by the formatting object to which they were returned. </p><p> A set of nodes in a tree is a <b>lineage</b> if: </p><ul><li><p> there is a node <var>N</var> in the set such that all the nodes in the set are ancestors of <var>N</var>, and</p></li><li><p> for every node <var>N</var> in the set, if the set contains an ancestor of <var>N</var>, it also contains the parent of <var>N</var>.</p></li></ul><p> The set of formatting objects that an area is returned by is a <b>lineage</b>. </p><p> Areas returned by a formatting object may be either <b>normal</b> or <b>out-of-line</b>. Normal areas represent areas in the "normal flow of text"; that is, they become area children of the areas generated by the formatting object to which they are returned. Normal areas have a <b>returned-by</b> lineage of size one. There is only one kind of normal area. </p><p> Out-of-line areas are areas used outside the normal flow of text either because they are absolutely positioned or they are part of a float or footnote. Out-of-line areas may have a <b>returned-by</b> lineage of size greater than one. </p><p> The <b>area-class</b> trait indicates which class, normal or out-of-line, an area belongs to. For out-of-line areas, it also indicates the subclass of out-of-line area. The values for this trait are: "xsl-normal", "xsl-absolute", "xsl-footnote", "xsl-side-float", or "xsl-before-float". An area is normal if and only if the value of the <b>area-class</b> trait is "xsl-normal"; otherwise, the area is an out-of-line area. (See section <a href="#area-stackcon"><b>4.2.5 Stacking Constraints</b></a>.)</p><p> The areas <b>returned-by</b> a given formatting object are ordered as noted above. This ordering defines an ordering on the sub-sequence of areas that are of a given <b>area-class</b>, such as the sub-sequence of normal areas. An area <var>A</var> precedes an area <var>B</var> in the sub-sequence if and only if area <var>A</var> precedes area <var>B</var> in the areas <b>returned-by</b> the formatting objects. </p><p>A <b>reference-area chain</b> is defined as a sequence of reference-areas that is either generated by the same formatting object that is not a page-sequence formatting object, or that consists of the region reference-areas or normal-flow-reference-areas (see <a href="#fo_region-body"><b>6.4.14 fo:region-body</b></a>) generated using region formatting objects assigned to the same flow (see <a href="#fafm"><b>6.4.1.4 Flows and Flow Mapping</b></a>). The reference-areas in the sequence are said to be "contained" by the reference-area chain, and they have the same ordering relative to each other in the sequence as they have in the area tree, using pre-order traversal order of the area tree.</p></div></div><div class="div2"> <h3><a name="d0e6532" id="d0e6532"></a>6.2 Formatting Object Content</h3><p>The content of a formatting object is described using XML content-model syntax.

The children of the fo:root formatting object are a single fo:layout-master-set, an optional fo:declarations, an optional fo:bookmark-tree, and a sequence of one or more fo:page-sequences and/or fo:page-sequence-wrapper elements. The fo:layout-master-set defines the geometry and sequencing of the pages; the children of the fo:page-sequences, which are called <b>flows</b> (contained in fo:flow and fo:static-content), provide the content that is distributed into the pages. The fo:declarations object is a wrapper for formatting objects whose content is to be used as a resource to the formatting process. The process of generating the pages is done automatically by the XSL processor formatting the result tree. </p><p>The children of the fo:layout-master-set are the pagination and layout specifications and flow-map specifications. There are two types of pagination and layout specifications: page-masters and page-sequence-masters. Page-masters have the role of describing the intended subdivisions of a page and the geometry of these subdivisions. Page-sequence-masters have the role of describing the sequence of page-masters that will be used to generate pages during the formatting of an fo:page-sequence. Flow-maps have the role of assigning flows to regions. </p><div class="div4"> <h5><a name="d0e7070" id="d0e7070"></a>6.4.1.1 Page-sequence-masters</h5><p>Each fo:page-sequence-master characterizes a set of possible sequences of page-masters. For any given fo:page-sequence, only one of the possible set of sequences will be used. The sequence that is used is any sequence that satisfies the constraints determined by the individual page-masters, the flows which generate pages from the page-masters, and the fo:page-sequence-master itself. </p><p>The fo:page-sequence-master is used to determine which page-masters are used and in which order. The children of the fo:page-sequence-master are a sequence of sub-sequence specifications. The page-masters in a sub-sequence may be specified by a reference to a single page-master or as a repetition of one or more page-masters. For example, a sequence might begin with several explicit page-masters and continue with a repetition of some other page-master (or masters). </p><p>The fo:single-page-master-reference is used to specify a sub-sequence consisting of a single page-master. </p><p>There are two ways to specify a sub-sequence that is a repetition. The fo:repeatable-page-master-reference specifies a repetition of a single page-master. The fo:repeatable-page-master-alternatives specifies the repetition of a set of page-masters. Which of the alternative page-masters is used at a given point in the sub-sequence is conditional and may depend on whether the page number is odd or even, is the first page, is the last page, or is blank. The "maximum-repeats" property on the repetition specification controls the number of repetitions. If this property is not specified, there is no limit on the number of repetitions. </p></div><div class="div4"> <h5><a name="d0e7081" id="d0e7081"></a>6.4.1.2 Page-masters</h5><p>A page-master is a master that is used to generate a <b>page</b>. A page is a viewport/reference pair in which the viewport-area is a child of the area tree root. A <b>page-viewport-area</b> is defined to be the viewport-area of a page, and a <b>page-area</b> is defined to be the unique child of a page-viewport-area. </p><p> The page-viewport-area is defined by the output medium; the page-area holds the page contents and has the effect of positioning the page contents on the output medium. </p><p>A single page-master may be used multiple times. Each time it is used it generates a single page; for example, a page-master that is referenced from an fo:repeatable-page-master-reference will be used by the fo:page-sequence to generate one page for each occurrence of the reference in the specified sub-sequence. </p><div class="note"><p class="prefix"><b>Note:</b></p><p>When pages are used with a User Agent such as a Web browser, it is common that the each document has only one page. The viewport used to view the page determines the size of the page. When pages are placed on non-interactive media, such as sheets of paper, pages correspond to one or more of the surfaces of the paper. The size of the paper determines the size of the page.</p></div><p>In this specification, there is only one kind of page-master, the fo:simple-page-master. Future versions of this specification may add additional kinds of page-masters. </p><p>An fo:simple-page-master has, as children, specifications for one or more regions. </p><p>A region specification is used as a master, the <b>region-master</b>, in generating a viewport/reference pair consisting of a <b>region-viewport-area</b> and a <b>region-reference-area</b>. The region-viewport-area is always a child of a page-area generated using the parent of the region-master. </p><div class="note"><p class="prefix"><b>Note:</b></p><p>The regions on the page are analogous to "frames" in an HTML document. Typically, at least one of these regions is of indefinite length in one of its dimensions. For languages with a lr-tb (or rl-tb) writing-mode, this region is typically of indefinite length in the top-to-bottom direction. The viewport represents the visible part of the frame. The flows assigned to the region are viewed by scrolling the region reference-area through the viewport. </p></div><p>Each region is defined by a region formatting object. Each region formatting object has a name and a definite position. In addition, the region's height or width is fixed and the other dimension may be either fixed or indefinite. For example, a region that is the body of a Web page may have indefinite height. </p><p>The specification of the region determines the size and position of region-viewport-areas generated using the region formatting object. The positioning of the viewport is relative to its page-area parent. </p><p>For version 1.1 of this Recommendation, a page-master will consist of the following regions: "region-body" (one or more) and four other regions, one on each side of the body. To allow the side regions to correspond to the current writing-mode, these regions are named "region-before" (which corresponds to "header" in the "lr-tb" writing-mode), "region-after" (which corresponds to "footer" in the "lr-tb" writing-mode), "region-start" (which corresponds to a "left-sidebar" in the "lr-tb" writing-mode) and "region-end" (which corresponds to a "right-sidebar" in the "lr-tb" writing-mode). It is expected that a future version of the Recommendation will introduce a mechanism that allows a page-master to contain an arbitrary number of arbitrarily sized and positioned regions.</p><p>Some types of region have conditional sub-regions associated with them, and the associated region-reference-areas are divided up by having child areas corresponding to the sub-regions, including a "main-reference-area" for the region. For region-masters to which the column-count property applies, the main-reference-area is further subdivided by having child-areas designated as "span-reference-areas" whose number depends upon the number of spans (i.e. block-areas with span="all") occurring on the page. These in turn are subdivided by having child-areas designated as "normal-flow-reference-areas", whose number depends on the number of columns specified.</p></div><div class="div4"> <h5><a name="d0e7128" id="d0e7128"></a>6.4.1.3 Page Generation</h5><p> Pages are generated by the formatter's processing of fo:page-sequences. As noted above, each page is a viewport/reference pair in which the viewport-area is a child of the area tree root. Each page is generated using a page-master to define the region-viewport-areas and region-reference-areas that correspond to the regions specified by that page-master. </p><p>Each fo:page-sequence references either an fo:page-sequence-master or a page-master. If the reference is to a page-master, this is interpreted as if it were a reference to an fo:page-sequence-master that repeats the referenced page-master an unbounded number of times. An fo:page-sequence references a page-master if either the fo:page-sequence directly references the page-master via the "master-reference" property or that property references an fo:page-sequence-master that references the page-master. </p></div><div class="div4"> <h5><a name="fafm" id="fafm"></a>6.4.1.4 Flows and Flow Mapping</h5><p>There are two kinds of <b>flows</b>: fo:static-content and fo:flow. An fo:static-content flow holds content, such as the text that goes into headers and footers, that is repeated on many of the pages. An fo:flow flow holds content that is distributed across a sequence of pages. The processing of the fo:flow flows is what determines how many pages are generated to hold the fo:page-sequence. The fo:page-sequence-master is used as the generator of the sequence of page-masters into which the flow children content is distributed. </p><p>The children of a flow are a sequence of block-level flow objects. Each flow has a name that is given by its "flow-name" property. No two flows that are children of the same fo:page-sequence may have the same name.</p><p>The assignment of flows to regions on a page-master is determined by a <b>flow-map</b>. The flow-map is an association between the flow children of the fo:page-sequence and regions defined within the page-masters referenced by that fo:page-sequence. </p><p>Flow-maps are specified by fo:flow-map formatting objects. An fo:page-sequence uses the flow-map indicated by its flow-map-reference property when assigning its flows to regions. If the flow-map-reference property is not specified for the page-sequence then the implicit flow-map is used for that page-sequence, as in version 1.0 of this Recommendation. The "flow-name" property of a flow specifies to which region that flow is assigned. Each region has a "region-name" property. The flow-map assigns a flow to the region that has the same name.</p><p>To avoid requiring users to generate region-names, the regions all have default values for the "region-name" property. The region-body, region-before, region-after, region-start, and region-end have the default names "xsl-region-body", "xsl-region-before", "xsl-region-after", "xsl-region-start", and "xsl-region-end", respectively. It is an error for a page master to have two region-body descendants with the default region-name.</p><p>In addition, an fo:static-content formatting object may have a "flow-name" property value of "xsl-before-float-separator" or "xsl-footnote-separator". If a conditional sub-region of the region-body is used to generate a reference-area on a particular page, the fo:static-content whose name corresponds to the conditional sub-region shall be formatted into the reference-area associated with the sub-region, as specified in <a href="#pg-out-of-line"><b>6.12.1.3 Conditional Sub-Regions</b></a>.</p></div><div class="div4"> <h5><a name="d0e7158" id="d0e7158"></a>6.4.1.5 Constraints on Page Generation</h5><p>The areas that are descendants of a page-area are constrained by the page-master used to generate the page-area and the flows that are assigned to the regions specified on the page-master. For fo:flow flows, the areas generated by the descendants of the flow are distributed across the pages in the sequence according to the flow-map in effect for that page-sequence. For fo:static-content flows, the processing of the flow is repeated for each page generated using a page-master having the region to which the flow is assigned with two exceptions: for an fo:static-content with a <b>flow-name</b> of <code>xsl-before-float-separator</code>, the processing is repeated only for those page-reference-areas which have descendant areas with an area-class of <code>xsl-before-float</code>, and for an fo:static-content with a <b>flow-name</b> of <code>xsl-footnote-separator</code>, the processing is repeated only for those page-reference-areas which have descendant areas with an area-class of <code>xsl-footnote</code>.</p></div><div class="div4"> <h5><a name="d0e7181" id="d0e7181"></a>6.4.1.6 Pagination Tree Structure</h5><p>The result tree structure is shown below.</p><div class="figure"> <p><img src="PageTree.gif" alt="Tree representation of the Formatting Objects for pagination"><span class="dlink">   <a href="longdesc/PageTree.html" title="Long description of illustration 'Tree representation of the Formatting Objects for pagination'">[D]</a></span></p> <p>Tree Representation of the Formatting Objects for Pagination</p> </div></div><div class="div4"> <h5><a name="d0e7194" id="d0e7194"></a>6.4.1.7 Example Flow Maps</h5><p>A typical use of flow maps are where there are two or more flows that each, independently of each other, flow into separate regions on the pages.

The content-rectangle of the region-viewport-area is indented from the content-rectangle of the page-reference-area by the values of the "margin-top", "margin-bottom", "margin-left" and "margin-right" properties. The values of the <b>padding</b> and <b>border-width</b> traits must be "0". </p><p> The region-reference-area generated using an fo:region-body is the child of the region-viewport-area. The "writing-mode" of the fo:region-body defines the column-progression within the region. The inline-progression-direction is used to determine the stacking direction for columns (and the default flow order of text from column-to-column). </p><p>In addition to the viewport/reference pair, when the region-body is used to generate areas, at least one and up to three additional reference-areas are generated. These reference-areas are the optional <b>before-float-reference-area</b>, the optional <b>footnote-reference-area</b>, and the <b>main-reference-area</b>. The latter reference-area comprises the space left after space is borrowed for the other two reference-areas.

The number and placement of the children of a span-reference-area depends on the <b>column-count</b> trait of the span-reference-area. In turn, the formatter must generate precisely enough of these span-reference-areas, and so set their <b>column-count</b> traits, that block-areas returned from the flows with a <b>span</b> of "all" are children of span-reference-areas with <b>column-count</b> equal to 1, and block-areas returned from the flows with a <b>span</b> of "none" are children of span-reference-areas with <b>column-count</b> equal to the refined value of the column-count property of the associated region-reference-area.</p><p>For each span-reference-area, the number <var>N</var> of normal-flow-reference-area children is equal to the value of the <b>column-count</b> trait.</p><p>It is an error to specify a <b>column-count</b> other than 1 if the "overflow" property has the value "scroll".

A complete table may be seen as consisting of a grid of rows and columns where each cell occupies one or more grid units in the row-progression-direction and column-progression-direction.</p><p>The table content is divided into a header (optional), footer (optional), and one or more bodies. Properties specify if the headers and footers should be repeated at a break in the table. Each of these parts occupies one or more rows in the table grid.</p><p><em>Areas:</em></p><p>The fo:table formatting object generates and returns one or more <b>normal</b> <b>block-area</b>s. These areas consist of the content of the fo:table-header (unless omitted as specified by the "table-omit-header-at-break" property), followed by some portion of the content of the fo:table-body(s), followed by the content of the fo:table-footer (unless omitted as specified by the "table-omit-footer-at-break" property). In addition the fo:table returns any <b>page-level-out-of-line</b> areas, and any <b>reference-level-out-of-line</b> areas returned by the children of the fo:table.</p><p>The areas generated and returned by the fo:table formatting object have as children:</p><ul><li><p>Areas, with only background, corresponding to the table-header, table-footer, table-body, spanned columns, columns, and rows. </p><div class="note"><p class="prefix"><b>Note:</b></p><p>The spanned columns (fo:table-column with a "number-columns-spanned" value greater than 1) are used in the same way as the "column groups" in CSS2 for determining the background.</p></div></li><li><p>Areas returned by the fo:table-cell formatting objects.</p></li></ul><p>These areas have a z-index controlling the rendering order determined in accordance with 17.5.1 of the CSS2 specification (<a href="https://www.w3.org/TR/REC-CSS2/tables.html#table-layers">http://www.w3.org/TR/REC-CSS2/tables.html#table-layers"</a>).</p><div class="note"><p class="prefix"><b>Note:</b></p><p>A cell that is spanned may have a different background in each of the grid units it occupies.</p></div><p><em>Trait Derivation:</em></p><p>The column-progression-direction and row-progression-direction are determined by the <b>writing-mode</b> trait.

The first, which is placed with the inside edge coincident with the outermost table grid boundary line, has the width of half the value for the "border-separation" property. It is filled in accordance with the "background" property of the fo:table. Second, outside the outermost table grid boundary line is placed, for each side of the table, a border based on a border specified on the table.</p><p>If the value of the "border-collapse" property is "collapse" or "collapse-with-precedence" the border is determined, for each segment, at the cell level.</p><div class="note"><p class="prefix"><b>Note:</b></p><p>By specifying "collapse-with-precedence" and an appropriately high precedence on the border specification for the fo:table one may ensure that this specification is the one used on all border segments.</p></div><p><em>Constraints:</em></p><p>No area may have more than one normal child area returned by the same fo:table formatting object.</p><p>The content of the fo:table-header and fo:table-footer, unless omitted as specified by the "table-omit-header-at-break" and "table-omit-footer-at-break" properties, shall be repeated for each normal block-area generated and returned by the fo:table formatting object.</p><p>The inline-progression-dimension of the content-rectangle of the table is the sum of the inline-progression-dimensions of the columns in the table grid. The method used to determine these inline-progression-dimensions is governed by the values of the <b>table-layout</b> and the <b>inline-progression-dimension</b> traits in the following manner:</p><dl><dt class="label">inline-progression-dimension="auto" table-layout="auto"</dt><dd><p>The automatic table layout shall be used.</p></dd><dt class="label">inline-progression-dimension="auto" table-layout="fixed"</dt><dd><p>The automatic table layout shall be used.</p></dd><dt class="label">inline-progression-dimension=<length> or <percentage> table-layout="auto"</dt><dd><p>The automatic table layout shall be used.</p></dd><dt class="label">inline-progression-dimension=<length> or <percentage> table-layout="fixed"</dt><dd><p>The fixed table layout shall be used.</p></dd></dl><p>The automatic table layout and fixed table layout is defined in 17.5.2 of the CSS2 specification (<a href="https://www.w3.org/TR/REC-CSS2/tables.html#width-layout">http://www.w3.org/TR/REC-CSS2/tables.html#width-layout"</a>).</p><p>The method for determining the block-progression-dimension of the table is governed by the <b>block-progression-dimension</b> trait.</p><div class="note"><p class="prefix"><b>Note:</b></p><p>The CSS2 specification explicitly does not specify what the behavior should be if there is a mismatch between an explicitly specified table block-progression-dimension and the block-progression-dimensions of the content.</p></div><div class="note"><p class="prefix"><b>Note:</b></p><p>The use of the "proportional-column-width()" function is only permitted when the fixed table layout is used.</p><p>If the use of proportional column widths are desired on a table of an unknown explicit width, the inline-progression-dimension cannot be specified to be "auto". Instead, the width must be specified as a percentage.

An implementation may recover from this error by repositioning the table-cells so that all of the content is shown.</p><p>Table-cells must each be entirely contained both horizontally and vertically in a single table-body, table-header or table-footer. It is therefore an error if table-cells attempt to span too far. This might for example happen in a table whose table-layout is fixed by having a number-rows-spanned or number-columns-spanned value larger than the number of available rows or columns in the spanned direction.

This can be used for, e.g., expandable/collapsible table of contents, display of an icon or a full table or graphic. </p></li><li><p>The ability to switch between different property values, such as color or font-weight, depending on a User Agent state, such as "hover". </p></li></ul><p>The switching between subtrees is achieved by using the following three formatting objects: fo:multi-switch, fo:multi-case, and fo:multi-toggle. The result tree structure is shown below. </p><div class="figure"> <p><img src="MultiSTree.gif" alt="Tree representation of the multi Formatting Objects"><span class="dlink">   <a href="longdesc/MultiSTree.html" title="Long description of illustration 'Tree representation of the multi Formatting Objects'">[D]</a></span></p> <p>Tree Representation of the Multi Formatting Objects</p> </div><p>The role of the fo:multi-switch is to wrap fo:multi-case formatting objects, each containing a subtree. Each subtree is given a name on the fo:multi-case formatting object. Activating, for example implemented as clicking on, an fo:multi-toggle causes a named subtree, the previous, the next, or "any" subtree to be displayed; controlled by the "switch-to" property. For "any", an implementation would typically present a list of choices each labeled using the "case-title" property of the fo:multi-case. The initial subtree displayed is controlled by the "starting-state" property on the fo:multi-case.</p><p>Switching between different property values is achieved by using the fo:multi-properties and fo:multi-property-set formatting objects, and the merge-property-values() function. For example, an fo:multi-property-set can be used to specify various properties for each of the possible values of the active-state property, and merge-property-values() can be used to apply them on a given formatting object.</p><div class="div4"> <h5><a name="d0e12887" id="d0e12887"></a>6.9.1.1 Examples</h5><div class="div5"> <h6><a name="d0e12890" id="d0e12890"></a>6.9.1.1.1 Expandable/Collapsible Table of Contents</h6><p>Input sample:</p><div class="exampleInner"><pre> <doc> <chapter><title>Chapter</title> <p>Text</p> <section><title>Section</title> <p>Text</p> </section> <section><title>Section</title> <p>Text</p> </section> </chapter> <chapter><title>Chapter</title> <p>Text</p> <section><title>Section</title> <p>Text</p> </section> <section><title>Section</title> <p>Text</p> </section> </chapter> </doc> </pre></div><p>In this example the chapter and section titles are extracted into a table of contents placed at the front of the result.

There are two kinds of such objects and properties: those that associate index keys with formatting objects throughout the tree and formatting objects that are used in the back-of-the-book index to assemble page references to the pages where the areas from formatting objects with a particular index key occur. Further formatting properties and objects control the way in which these page references are grouped and arranged into ranges.</p><p>There are two properties for associating index keys with formatting objects: "index-key" and "index-class". These two properties apply to almost all formatting objects. There are two formatting objects for associating explicit index key ranges, fo:index-range-begin and fo:index-range-end.</p><p>Cited page items associated with a particular index key are obtained using the fo:index-key-reference. Its parent, fo:index-page-citation-list, groups and arranges these. In addition, the form of the generated page number list can be defined and controlled using the formatting objects fo:index-page-number-prefix, fo:index-page-number-suffix, fo:index-page-citation-list-separator, and fo:index-page-citation-range-separator. For a back-of-the-book index each index term would have an index key that is used to identify each occurrence of that term within the document. In the back-of-the-book index there would be at least one fo:index-key-reference for each index key used. For example,</p><div class="exampleInner"><pre> <fo:block>Eiffel Tower <fo:index-page-citation-list> <fo:index-key-reference ref-index-key="Eiffel Tower;;"/> </fo:index-page-citation-list> </fo:block> </pre></div><p>The structure and content of the generated list of page numbers can be further controlled through the use of index classes to distinguish different types of index entries or to distinguish entries present in different parts of the document. For example, different classes could be used to distinguish index entries for figures from normal entries or to distinguish entries within one section, e.g. the preface, of a document from entries from another section, e.g. the main body, in order to control the construction of page ranges. The fo:index-page-number-prefix and fo:index-page-number-suffix specify additional text, e.g. "[" and "]", to surround the page numbers in the index.</p><div class="note"><p class="prefix"><b>Note:</b></p><p>The formatting objects for indexing only provide facilities for generating the list of page numbers for individual index keys. Assembling the index entries; identifying all the entries, sorting them, and creating the formatting objects, e.g. fo:block, and text, e.g. "Eiffel Tower", for the entry and referencing the appropriate index key, e.g. "Eiffel Tower;;", is done by the general stylesheet mechanisms.</p></div><div class="div4"> <h5><a name="d0e13312" id="d0e13312"></a>6.10.1.1 Example</h5><p>The following example document is used throughout this section to describe the indexing process and how the various options change the presentation of the index.</p><p>The source document uses typical XML markup for representing back-of-the-book index entries.

In this example index terms may be primary, secondary, or tertiary, reflecting a typical multi-level index. Primary entries may have subordinate secondary entries. Secondary entries may have subordinate tertiary entries. For this document only the lowest-level entries are associated with page numbers (which means that each "indexterm" element can be simply translated into an index key value by concatenating the primary, secondary, and tertiary term values with some separator, ";" in this example, between them). </p><ul><li><p>Each individual reference to the tower is identified:</p><div class="exampleInner"><pre> <indexterm><primary>Eiffel Tower</primary></indexterm> </pre></div></li><li><p>Some of these terms identify a preferred description of the tower:</p><div class="exampleInner"><pre> <indexterm significance="preferred"> <primary>Eiffel Tower</primary></indexterm> </pre></div></li><li><p>For a long description of the tower, individual terms mark the beginning and end of the span:</p><div class="exampleInner"><pre> <indexterm id="ei.idx" class="startofrange"> <primary>Eiffel Tower</primary></indexterm> ... <indexterm startref="ei.idx" class="endofrange"/> </pre></div></li><li><p>Two of the terms occur inside figures:</p><div class="exampleInner"><pre> <figure id="tower1"> <head>The Eiffel Tower</head> <indexterm><primary>Eiffel Tower</primary></indexterm> ... </figure> </pre></div></li></ul><div class="div5"> <h6><a name="d0e13429" id="d0e13429"></a>6.10.1.1.1 Associating Index Keys with Formatting Objects</h6><p>The first step in generating an index is to transfer the index term information from the source document into the formatting objects.

These details are not considered here.</p><div class="note"><p class="prefix"><b>Note:</b></p><p>Index cross references ("see" and "see also" entries) are not associated with page numbers, so they do not use the indexing formatting objects.</p></div><p>This section describes the formatting objects used for collating and sorting the lists of page number citations associated with <i>each entry</i> in the index. The formatting objects referenced by index keys are used to generate sets of cited page items referencing sets of pages from the paginated area tree. These cited page items are then collated, sorted, and possibly collapsed into cited page item ranges, and then the final formatting processing is applied. That is, the index processing starts as references to formatting objects by index key, moves to the domain of real pages on which those formatting objects fall, and then, once the lists of pages have been reduced to sets and ranges, results in formatted lists of page numbers and ranges.</p><p>The fo:index-page-citation-list formatting object is used to group index key references together. Its ultimate effect is to produce a formatted list of page numbers and ranges. The starting set of cited page items is created using "fo:index-key-reference" formatting objects. Each fo:index-key-reference formatting object uses a single index key to generate cited page items for the pages on which the formatting objects with that key occur. The fo:index-key-reference also provides the formatting properties for these page numbers. All of the cited page items generated from a single fo:index-page-citation-list formatting object are sorted and collated together.</p><p>For this example, the formatting style is to distinguish pages that have the principal description of an item by using bold page numbers and to enclose in square brackets the page numbers where the index key occured in a figure. The following formatting objects accomplish this:</p><div class="exampleInner"><pre> <fo:index-page-citation-list merge-sequential-page-numbers="merge"/> <fo:index-key-reference ref-index-key="Eiffel Tower;;;preferred" font-weight="bold" id="XB"/> <fo:index-key-reference ref-index-key="Eiffel Tower;;;figure" font-style="italic" id="XI"> <fo:index-page-number-prefix> <fo:inline>[</fo:inline> </fo:index-page-number-prefix> <fo:index-page-number-suffix> <fo:inline>]</fo:inline> </fo:index-page-number-suffix> </fo:index-key-reference> <fo:index-key-reference ref-index-key="Eiffel Tower;;" id="XX"/> </fo:index-page-citation-list> </pre></div><p>In this index page citation list, three different groups of page citations, represented by references to three different, but related, keys, are merged into a single result list of page citations. </p><div class="note"><p class="prefix"><b>Note:</b></p><p>The "id" values on the fo:index-key-reference formatting objects are for reference purposes in the text below.

First, so that during the normal placement of content, some related content is formatted into a separate area at the beginning of a page where it is available to be read without immediately intruding on the reader. The areas generated by this kind of fo:float are called before-floats. An fo:float is specified to generate before-floats if it has a "float" property value of "before". The constraints on placing before-floats on a page are described in the <a href="#pg-out-of-line"><b>6.12.1.3 Conditional Sub-Regions</b></a> section of this introduction and in the description of the fo:float formatting object.</p><p>Second, the fo:float formatting object is used when an area is intended to float to one side, with normal content flowing alongside the floated area. The areas generated by this kind of fo:float are called side-floats. A side-float is always made a child of the nearest ancestor reference-area. The edge of the reference-area towards which the side-float floats is controlled by the value of the "float" property.</p><p>Flowing normal content flowing alongside side-floats is realized by increasing the start-intrusion-adjustment or the end-intrusion-adjustment of normal child areas of the parent reference-area of the side-float.</p><p>The "clear" property applies to any block-level formatting object. If the value of this property for a particular formatting object is any value other than "none", then the areas generated by the block will be positioned to ensure that their border-rectangles do not overlap the allocation-rectangles of the applicable side-floats as determined by the "clear" property value.</p></div><div class="div4"> <h5><a name="d0e14359" id="d0e14359"></a>6.12.1.2 Footnotes</h5><p>The fo:footnote formatting object is used to generate both a footnote and its citation. The fo:footnote has two children, which are both required to be present. The first child is an fo:inline formatting object, which is formatted to produce the footnote citation. The second child is an fo:footnote-body formatting object which generates the content (or body) of the footnote.</p><p>The actual areas generated by the descendants of the fo:footnote-body formatting object are determined by the formatting objects that comprise the descendant subtree. For example, the footnote could be formatted with a label and an indented body by using the fo:list-block formatting object within the fo:footnote-body.</p></div><div class="div4"> <h5><a name="pg-out-of-line" id="pg-out-of-line"></a>6.12.1.3 Conditional Sub-Regions</h5><p>The region-body has two conditional sub-regions which implicitly specify corresponding reference-areas called <b>before-float-reference-area</b> and <b>footnote-reference-area</b>. These reference-areas are conditionally generated as children of the region-reference-area. The before-float-reference-area is generated only if the page contains one or more areas with area-class "xsl-before-float". The footnote-reference-area is generated only if the page contains one or more areas with area-class "xsl-footnote". </p><p>The conditionally generated areas borrow space in the <b>block-progression-dimension</b> (this is "height" when the writing-mode is "lr-tb") within the region-reference-area, at the expense of the main-reference-area. Whether or not a conditionally generated area is actually generated depends, additionally, on whether there is sufficient space left in the main-reference-area. </p><p>There may be limits on how much space conditionally generated areas can borrow from the region-reference-area. It is left to the user agent to decide these limits. </p><p>The block-progression-dimension of the main-reference-area is set equal to the block-progression-dimension of the allocation-rectangle of the region-reference-area minus the sum of the sizes in the block-progression-direction of the allocation-rectangles of the conditionally generated reference-areas that were actually generated. The main-reference-area is positioned to immediately follow the after-edge of the allocation-rectangle of the before-float-reference-area. This positions the after-edge of the main-reference-area to coincide with the before-edge of the allocation-rectangle of the footnote-reference-area. In addition to the constraints normally determined by the region-reference-area, the <b>inline-progression-dimension</b> (this is "width" when the writing-mode is "lr-tb") of a conditionally generated reference-area is constrained to match the inline-progression-dimension of the main-reference-area. </p><p>Each conditionally generated reference-area may additionally contain a sequence of areas used to separate the reference-area from the main-reference-area. The sequence of areas is the sequence returned by formatting an fo:static-content specified in the page-sequence that is being used to format the page.</p><p>If there is an fo:static-content in a page-sequence whose "flow-name" property value is "xsl-before-float-separator", then the areas returned by formatting the fo:static-content are inserted in the proper order as the last children of a before-float-reference-area that is generated using the same page-master, provided the main-reference-area on the page is not empty.</p><p>If there is an fo:static-content whose "flow-name" property value is "xsl-footnote-separator", then the areas returned by formatting the fo:static-content are inserted in the proper order as the initial children of a footnote-reference-area that is generated using the same page-master.</p><p>An interactive user agent may choose to create "hot links" to the footnotes from the footnote-citation, or create "hot links" to the before-floats from an implicit citation, instead of realizing conditional sub-regions. </p><p>The generation of areas with area-class "xsl-before-float" or "xsl-footnote" is specified in the descriptions of the formatting objects that initially return areas with those area-classes.</p></div><div class="div4"> <h5><a name="d0e14399" id="d0e14399"></a>6.12.1.4 Examples</h5><div class="div5"> <h6><a name="d0e14402" id="d0e14402"></a>6.12.1.4.1 Floating Figure</h6><p>Input sample:</p><div class="exampleInner"><pre> <doc> <p>C'ieng pieces were made in northern towns, such as C'ieng Mai.

This model is described in this section and is based on current font technology as exemplified by the OpenType specification <a href="#OpenType">[OpenType]</a>. </p><p> A font consists of a collection of glyphs together with the information, the font tables, necessary to use those glyphs to present characters on some medium. A glyph is a recognizable abstract graphic symbol which is independent of any specific design. The combination of the collection of glyphs and the font tables is called the font data. </p><p> The font tables include the information necessary to map characters to glyphs, to determine the size of glyph areas and to position the glyph area. Each font table consists of one or more font characteristics, such as the font-weight and font-style. </p><p> The geometric font characteristics are expressed in a coordinate system based on the em box. (The em is a relative measure of the height of the glyphs in the font; see <a href="#relative.lengths"><b>5.9.7.2 Relative Lengths</b></a>.) This box that is 1 em high and 1 em wide is called the design space. Points in this design space are expressed in geometric coordinates in terms of fractional units of the em. </p><p> The coordinate space of the em box is called the design space coordinate system. For scalable fonts, the curves and lines that are used to draw a glyph are represented using this coordinate system. </p><div class="note"><p class="prefix"><b>Note:</b></p><p> Most often, the (0,0) point in this coordinate system is positioned on the left edge of the em box, but not at the bottom left corner. The Y coordinate of the bottom of a Roman capital letter is usually zero. In addition, the descenders on lower case Roman letters have negative coordinate values. </p></div><p> XSL assumes that the font tables will provide at least three font characteristics: an ascent, a descent and a set of baseline-tables. The coordinate values for these are given in the design space coordinate system. The ascent is given by the vertical coordinate of the top of the em box; the descent is given by the vertical coordinate of the bottom of the em box. The baseline-table is explained below. </p><p> The glyphs of a given script are positioned so that a particular point on each glyph, the <b>alignment-point</b>, is aligned with the alignment-points of the other glyphs in that script. The glyphs of different scripts are typically aligned at different points on the glyph. For example, Western glyphs are aligned on the bottoms of the capital letters, certain Indic glyphs (including glyphs from the Devanagari, Gurmukhi and Bengali scripts) are aligned at the top of a horizontal stroke near the top of the glyphs and Far Eastern glyphs are aligned either at the bottom or center of the em box of the glyph. Within a script and within a line of text having a single font-size, the sequence of alignment-points defines, in the inline-progression-direction, a geometric line called a <b>baseline</b>. Western and most other alphabetic and syllabic glyphs are aligned to an "alphabetic" baseline, the above Indic glyphs are aligned to a "hanging" baseline and the Far Eastern glyphs are aligned to an "ideographic" baseline. </p><div class="figure"> <p><img src="AlignmentPointsMixedScripts2.gif" alt="Three examples of baselines"><span class="dlink">   <a href="longdesc/AlignmentPointsMixedScripts2.html" title="Long description of illustration 'Three examples of baselines'">[D]</a></span></p> <p> This figure shows the vertical position of the alignment-point for alphabetic and many syllabic scripts, illustrated by a Roman "A"; for certain Indic scripts, illustrated by a Gurmukhi syllable "ji"; and for ideographic scripts, illustrated by the ideograhic glyph meaning "country". The thin black rectangle around the ideographic glyph illustrates the em box for that glyph and shows the typical positioning of the "black marks" of the glyph within the em box. </p> </div><p> A <b>baseline-table</b> specifies the position of one or more baselines in the design space coordinate system. The function of the baseline table is to facilitate the alignment of different scripts with respect to each other when they are mixed on the same text line. Because the desired relative alignments may depend on which script is dominant in a line (or block), there may be a different baseline table for each script. In addition, different alignment positions are needed for horizontal and vertical writing modes. Therefore, the font may have a set of baseline tables: typically, one or more for horizontal writing-modes and zero or more for vertical writing-modes. </p><div class="figure"> <p><img src="Baselines-HorizAndVert-ApCountry.gif" alt="Horizontal and vertical baseline alignment"><span class="dlink">   <a href="longdesc/Baselines-HorizAndVert-ApCountry.html" title="Long description of illustration 'Horizontal and vertical baseline alignment'">[D]</a></span></p> <p> Examples of horizontal and vertical baseline positions. The thin lined box in each example is the "em box". For the Latin glyphs, only the em box of the first glyph is shown. Example 1 shows typical Latin text written horizontally. This text is positioned relative to the alphabetic baseline, shown in blue. Example 2 shows a typical ideographic glyph positioned on the horizontal ideographic baseline. Note that the em box is positioned differently for these two cases. Examples 3 and 4 show the same set of baselines used in vertical writing. The Latin text, example 3, is shown with a glyph-orientation of 90 degrees which is typical for proportionally space Latin glyphs in vertical writing. Even though the ideographic glyph in example 4 is positioned on the vertical ideographic baseline, because it is centered in the em box, all glyphs with the same em box are centered, vertically, with respect to one another. Additional examples showing the positioning of mixed scripts are given in the introductions to <a href="#area-alignment"><b>7.14 Area Alignment Properties</b></a> and <a href="#writing-mode-related"><b>7.29 Writing-mode-related Properties</b></a>. </p> </div><p> The font tables for a font include font characteristics for the individual glyphs in the font. XSL assumes that the font tables include, for each glyph in the font, one width value, one alignment-baseline and one alignment-point for the horizontal writing-modes. If vertical writing-modes are supported, then each glyph must have another width value, alignment-baseline and alignment-point for the vertical writing-modes. (Even though it is specified as a width, for vertical writing-modes the width is used in the vertical direction.) </p><p> The script to which a glyph belongs determines an alignment-baseline to which the glyph is to be aligned. The position of this baseline in the design space coordinate system determines the default block-progression-direction position of the alignment-point. The inline-progression-direction position of the alignment-point is on the start-edge of the glyph. (These positions are adjusted according to the specifications in <a href="#alignment-adjust"><b>7.14.1 alignment-adjust</b></a> when an instance of a glyph is used in an inline or block formatting object. The "space-start" and/or the "space-end" properties of the fo:character that maps to the glyph may be adjusted to effect "kerning" with respect to adjacent glyphs.) </p><div class="figure"> <p><img src="AlignmentPointsMixedScriptsOnBaselines.gif" alt="Baseline alignment of glyphs from different scripts"><span class="dlink">   <a href="longdesc/AlignmentPointsMixedScriptsOnBaselines.html" title="Long description of illustration 'Baseline alignment of glyphs from different scripts'">[D]</a></span></p> <p> This figure shows glyphs from three different scripts, each with its em box and within the em box, the baseline table applicable to that glyph. The alignment-point of each glyph is shown by an "X" on the start edge of the em box and by making alignment-baseline blue. The baseline-table of the parent formatting object of the characters that mapped to these glyphs is shown as a set of dashed lines. </p> </div><p> In addition to the font characteristics required above, a font may also supply substitution and positioning tables that can be used by a formatter to re-order, combine, and position a sequence of glyphs to make one or more composite glyphs. The combination may be as simple as a ligature, or as complex as an Indic syllable which combines, usually with some re-ordering, multiple consonants and vowel glyphs.

The higher the aspect value, the more likely it is that a font at smaller sizes will be legible. Inversely, faces with a lower aspect value will become illegible more rapidly below a given threshold size than faces with a higher aspect value. Straightforward font substitution that relies on font size alone may lead to illegible characters. </p> <p>For example, the popular font Verdana has an aspect value of 0.58; when Verdana's font size 100 units, its x-height is 58 units. For comparison, Times New Roman has an aspect value of 0.46. Verdana will therefore tend to remain legible at smaller sizes than Times New Roman. Conversely, Verdana will often look 'too big' if substituted for Times New Roman at a chosen size.</p> <p>This property allows authors to specify an aspect value for an element that will preserve the x-height of the first choice font in the substitute font. Values have the following meanings: </p> <dl><dt class="label">none</dt><dd><p>Do not preserve the font's x-height.</p></dd><dt class="label"><number></dt><dd><p>Specifies the aspect value.

If any of the values '600', '700', '800', or '900' remains unassigned, they are assigned to the same face as the next darker assigned keyword, if any, or the next lighter one otherwise.

The parent area is given a frame of reference through its scaled-baseline-table. A <b>scaled-baseline-table</b> is a compound value with three components: a baseline-identifier for the dominant-baseline, a derived baseline-table with positions for the baselines expressed in design space coordinates, and a baseline-table font-size that is used to scale the positions of the baselines in that baseline table. In a scaled-baseline-table, the positions of the baselines can be adjusted by multiplying the design-space coordinate values by the baseline-table font-size. </p><p> The positions of these baselines are illustrated in the following figure: </p><div class="figure"> <p><img src="Baselines-rev.gif" alt="Example of alignment of different scripts"><span class="dlink">   <a href="longdesc/Baselines-rev.html" title="Long description of illustration 'Example of alignment of different scripts'">[D]</a></span></p> <p> This figure shows samples of Gurmukhi (a hanging Indic script), Latin and ideographic scripts together with most of the baselines defined below. The thin line around the ideographic glyphs symbolizes the em box in which these glyphs are centered. In this figure, the position of the "text-before-edge" and "text-after-edge" baselines is computed assuming that the "alphabetic" baseline is the dominant-baseline. The "central" baseline has been omitted from the figure, but it lies halfway between the "text-before-edge" and "text-after-edge" baselines, just about where the "math" baseline is shown. </p> </div><p>The baseline-identifiers below are used in this specification. Some of these are determined by baseline-tables contained in a font as described in <a href="#font-model"><b>7.9.1 Fonts and Font Data</b></a>.

Examples 3 and 4 show defaulting to the "text-before-edge" when all the areas have either "before-edge" or "after-edge" alignment. In example 3, the images with "before-edge" alignment has a taller member than do the "after-edge" aligned images. In example 4, the tallest image is in the "after-edge" aligned set. Example 5 is a repetition of example 2 with largest image being an "after-edge" aligned image. </p> </div><p> The alignment of a formatting object with respect to its parent is determined by three things: the scaled-baseline-table of the parent and the alignment-baseline and alignment-point of the formatting object being aligned. Prior to alignment, the scaled-baseline-table of the parent may be shifted. The property specifications below provide the information necessary to align the parent and child formatting objects. </p><p> There are four properties that control alignment of formatting objects to the above set of baselines. These properties are all independent and are designed so that typically only the specification of one of the properties is needed to achieve a particular alignment goal. </p><p> The primary baseline alignment property is the "dominant-baseline" property. This property has a compound value with three components. The dominant-baseline-identifier component is the default alignment-baseline to be used when aligning two inline-areas. The baseline-table component specifies the positions of the baselines in the font design space coordinates. (See <a href="#font-model"><b>7.9.1 Fonts and Font Data</b></a>.) The baseline-table acts something like a musical staff; it defines particular points along the <b>block-progression-direction</b> to which glyphs and inline formatting objects can be aligned. The baseline-table font-size component provides a scaling factor for the baseline-table. </p><p> For convenience, the specification will sometimes refer to the baseline identified by the dominant-baseline-identifier component of the "dominant-baseline" property as the "dominant baseline" (in an abuse of terminology). </p><p> A simple example of alignment is shown in the following figure. The figure shows the presentation of two inline formatting objects, one inside the other. These inline formatting objects make up the content of a line in a block where the writing-mode is "lr-tb" and the font is "Helvetica". The structure of the example is as follows: </p><p> </p><pre><fo:inline>Apex <fo:inline>Top</fo:inline></fo:inline></pre><p> </p><p> Because no properties are specified, the initial values apply. Since a horizontal writing-mode is in use, the dominant-baseline-identifier is set to "alphabetic" and the baseline-table is taken from the nominal-font for the block in which the line appears, which, in this case, is Helvetica. </p><p> In the figure, the positions of the baselines relative to the current font size are shown as red (staff) lines. These lines are labeled with abbreviations of the names of the baselines (e.g., TBE for "text-before-edge"). The baseline identified by the dominant-baseline-identifier (A) is shown in blue. There is a break in the staff lines to separately show the inner inline formatting object. This is not necessary for this example, but this distinction will become important in subsequent examples. </p><p> The "alignment-baseline" property is the primary control on the positioning of an inner formatting object with respect to its parent. For all but fo:character, the initial value of the "alignment-baseline" property is "baseline". This aligns the dominant-baseline of the inner inline formatting object with the dominant baseline of the outer inline formatting object. This is shown by the short blue line that connects the two separated staffs (A) in the figure. </p><p> The glyphs determined by the fo:characters that are in the content of the two formatting objects are aligned based on the script to which the glyph belongs. Since this example only has Latin glyphs, they are aligned to the "alphabetic" baseline. </p><div class="figure"> <p><img src="AlignIntro-1.gif" alt="An inner inline formatting object containing Latin characters aligned to an outer inline formatting object also containing Latin characters."><span class="dlink">   <a href="longdesc/AlignIntro-1.html" title="Long description of illustration 'An inner inline formatting object containing Latin characters aligned to an outer inline formatting object also containing Latin characters.'">[D]</a></span></p> <p>An inner inline formatting object containing Latin characters aligned to an outer inline formatting object also containing Latin characters.</p> </div><p> In the next figure, the content of the inner inline formatting object is in Gurmukhi, the script of the Punjabi language.

The structure of the example becomes: </p><p> </p><pre><fo:inline>Apex <fo:inline><em>guru</em></fo:inline></fo:inline></pre><p> </p><p> The only change from the previous example is that the glyphs of the Gurmukhi script are aligned to the "hanging" baseline of the inner inline formatting object. The alignment of that formatting object itself, with respect to the outer inline formatting object, is unchanged. </p><div class="figure"> <p><img src="AlignIntro-2.gif" alt="An inner inline formatting object containing Gurmukhi characters aligned to an outer inline formatting object containing Latin characters."><span class="dlink">   <a href="longdesc/AlignIntro-2.html" title="Long description of illustration 'An inner inline formatting object containing Gurmukhi characters aligned to an outer inline formatting object containing Latin characters.'">[D]</a></span></p> <p>An inner inline formatting object containing Gurmukhi characters aligned to an outer inline formatting object containing Latin characters.</p> </div><p> In the next figure, fragments of the text of the previous examples make up the content of the outer inline formatting object. The inner inline formatting object has a change of font-size, however. The structure is: </p><p> </p><pre><fo:inline>Ap<em>guru</em> <fo:inline font-size='.75em'> Ex<em>ji</em> </fo:inline> </fo:inline></pre><p> </p><p> In this example, the alignment of the inner inline formatting object itself does not change, nor does the alignment of the smaller glyphs inside the inner formatting object. The Latin glyphs are still aligned to the "alphabetic" baseline and the Gurmukhi glyphs, which are pronounced "ji" are aligned to the "hanging" baseline. Note also that just changing the "font-size" property did not change the baseline-table in effect in the inner inline formatting object. </p><div class="figure"> <p><img src="AlignIntroB-2FS.gif" alt="Inline alignment of glyphs with reduced font-size"><span class="dlink">   <a href="longdesc/AlignIntroB-2FS.html" title="Long description of illustration 'Inline alignment of glyphs with reduced font-size'">[D]</a></span></p> <p>The inner inline formatting object has a reduced font-size.</p> </div><p> The next figure is equivalent to the previous example with the Gurmukhi character replaced by ideographic characters. These are aligned to the "ideographic" baseline. </p><div class="figure"> <p><img src="AlignIntroB-4FS.gif" alt="Inline alignment of glyphs with reduced font-size, continued"><span class="dlink">   <a href="longdesc/AlignIntroB-4FS.html" title="Long description of illustration 'Inline alignment of glyphs with reduced font-size, continued'">[D]</a></span></p> <p>The previous figure re-done with ideographic glyphs instead of Gurmukhi glyphs. The em boxes are shown for the ideograms to clarify the alignment of these glyphs. </p> </div><p> To change the scaling of the lines of the baseline table, it is necessary to use the "dominant-baseline" property on the inner inline formatting object. The value of "reset-size" causes the baseline-table font-size to be reset from the font-size of the formatting object on which the "dominant-baseline" property appears. The next figure shows the effect of this, using the structure: </p><p> </p><pre><fo:inline>Ap<em>guru</em> <fo:inline font-size='.75em' dominant-baseline='reset-size'> Ex<em>ji</em> </fo:inline> </fo:inline></pre><p> </p><p> The alignment of the inner inline formatting object, with respect to the outer inline formatting object, is still determined by aligning the dominant baselines. But, the baseline-table of the inner inline formatting object has been rescaled to the font-size of the inner inline formatting object. Hence the smaller glyphs align with each other. </p><div class="figure"> <p><img src="AlignIntroB-3RS.gif" alt="Inline alignment of glyphs with reduced font-size, continued"><span class="dlink">   <a href="longdesc/AlignIntroB-3RS.html" title="Long description of illustration 'Inline alignment of glyphs with reduced font-size, continued'">[D]</a></span></p> <p>The baseline-table of the inner inline formatting object has been re-sized to match the font-size of the inner inline formatting object.</p> </div><p> But, what if it is more important that the small Gurmukhi glyphs align with the large Gurmukhi glyphs than having the Latin glyphs align. There are at least two ways to achieve this. The structure: </p><p> </p><pre><fo:inline dominant-baseline='hanging'>Ap<em>guru</em> <fo:inline font-size='.75em' dominant-baseline='reset-size'> Ex<em>ji</em> </fo:inline> </fo:inline></pre><p> </p><p> is illustrated in the next figure. The "hanging" baseline becomes the dominant baseline and the initial value of the "alignment-baseline" property causes the (newly) dominant "hanging" baselines to be aligned as is shown by the connection of the blue baselines. </p><div class="figure"> <p><img src="AlignIntroB-3DH.gif" alt="Inline alignment of glyphs with reduced font-size, continued"><span class="dlink">   <a href="longdesc/AlignIntroB-3DH.html" title="Long description of illustration 'Inline alignment of glyphs with reduced font-size, continued'">[D]</a></span></p> <p>Changing the dominant baseline to the "hanging" baseline causes the inner inline formatting object to be aligned on its parent's "hanging" baseline.</p> </div><p> It is also possible to achieve the effect of the above figure without changing the dominant baseline. Instead it is sufficient to explicitly specify that the inner inline formatting object is aligned on its "hanging" baseline. This is done by: </p><p> </p><pre><fo:inline>Ap<em>guru</em> <fo:inline font-size='.75em' dominant-baseline='reset-size' alignment-baseline='hanging'> Ex<em>ji</em> </fo:inline> </fo:inline></pre><p> </p><p> The only change this approach would make in the above figure is to color the "hanging" baseline red and keep the "alphabetic" baseline as the (blue) dominant baseline. This baseline in the inner inline formatting object would not (as it does not in the above figure) align with the "alphabetic" baseline in the outer inline formatting object. </p><p> The third baseline alignment property is the "baseline-shift" property. Like the properties other than the "dominant-baseline" property, this property does not change the baseline-table or the baseline-table font-size. It does shift the whole baseline table of the parent formatting object so that when an inner inline formatting object is aligned to one of the parents baselines, the position of the inner inline formatting object is shifted. This is illustrated in the next figure. The structure which creates this figure is: </p><p> </p><pre> <fo:inline>Ap <fo:inline baseline-shift='super'>1<em>ji</em></fo:inline> </fo:inline> </pre><p> </p><p> Because the whole set of baseline-table staff lines are shifted to the position of the superscript baseline: it does not matter to which baseline the glyphs in the superscript are aligned. The European number "1" is aligned to the "alphabetic" baseline and the Gurmukhi syllable "ji" is aligned to the "hanging" baseline. </p><div class="figure"> <p><img src="AlignIntroB-5.gif" alt="Using a 'baseline-shift' for a superscript"><span class="dlink">   <a href="longdesc/AlignIntroB-5.html" title="Long description of illustration 'Using a 'baseline-shift' for a superscript'">[D]</a></span></p> <p>Using a "baseline-shift" for a superscript (or a subscript).</p> </div><p> It is more common for the font-size of the superscript text to be smaller than the font-size of the text to which it is appended.

After the rescaling, the default alignment to the dominant baseline positions the inline formatting object for the superscript to the dominant baseline position in the shifted baseline-table of the parent formatting object. </p><div class="figure"> <p><img src="AlignIntroB-5FS.gif" alt="Alignment of superscripts with reduces fonts"><span class="dlink">   <a href="longdesc/AlignIntroB-5FS.html" title="Long description of illustration 'Alignment of superscripts with reduces fonts'">[D]</a></span></p> <p>Reducing the font-size of the superscript automatically resets the baseline-table size so that mixed languages in the superscript stay mutually aligned.</p> </div><p> The fourth alignment property is the "alignment-adjust" property. This property is primarily used for objects, such as some graphics, that do not belong to a particular script and do not have a predefined alignment point. The "alignment-adjust" property allows the author to assign where, on the start-edge of the object, the alignment point for that object lies. </p><div class="div3"> <h4><a name="alignment-adjust" id="alignment-adjust"></a>7.14.1 "alignment-adjust"</h4><p>XSL Definition:</p><table border="0" class="prop-summary"><tbody valign="top" align="left"><tr valign="top" align="left"><td align="left" valign="top"><em>Value: </em></td><td align="left" valign="top">auto | baseline | before-edge | text-before-edge | middle | central | after-edge | text-after-edge | ideographic | alphabetic | hanging | mathematical | <percentage> | <length> | inherit</td></tr><tr valign="top" align="left"><td align="left" valign="top"><em>Initial: </em></td><td align="left" valign="top">auto</td></tr><tr valign="top" align="left"><td align="left" valign="top"><em>Inherited: </em></td><td align="left" valign="top">no</td></tr><tr valign="top" align="left"><td align="left" valign="top"><em>Percentages: </em></td><td align="left" valign="top">see prose</td></tr><tr valign="top" align="left"><td align="left" valign="top"><em>Media: </em></td><td align="left" valign="top">visual</td></tr></tbody></table><p>The "alignment-adjust" property allows more precise alignment of areas generated by formatting objects, in particular for formatting objects, such as graphics, that do not have a baseline-table or lack the desired baseline in their baseline-table.

For "alignment-adjust" the percentage values refer to the "line-height" of the area being aligned. For "baseline-shift" the percentage values refer to the "line-height" of the parent. Similarly, it is the "sub" and "super" offsets of the parent that are used to align the shifted baseline rather than the "sub" or "super" offsets of the areas being positioned. To ensure a consistent subscript or superscript position, it makes more sense to use the parent as the reference rather than the subscript formatting object which may have a changed "line-height" due to "font-size" changes in the subscript or superscript formatting object. </p><p>Using the "alignment-adjust" property is more suitable for positioning objects, such as graphics, that have no internal textual structure. Using the "baseline-shift" property is intended for subscripts and superscripts where the positioned object may itself be a textual object. The baseline-shift provides a way to define a specific baseline offset other than the named offsets that are defined relative to the dominant-baseline. In addition, having "baseline-shift" makes it easier for tool to generate the relevant properties; many formatting programs already have a notion of baseline shift. </p></div></div><div class="div3"> <h4><a name="display-align" id="display-align"></a>7.14.4 "display-align"</h4><p>XSL Definition:</p><table border="0" class="prop-summary"><tbody valign="top" align="left"><tr valign="top" align="left"><td align="left" valign="top"><em>Value: </em></td><td align="left" valign="top">auto | before | center | after | inherit</td></tr><tr valign="top" align="left"><td align="left" valign="top"><em>Initial: </em></td><td align="left" valign="top">auto</td></tr><tr valign="top" align="left"><td align="left" valign="top"><em>Inherited: </em></td><td align="left" valign="top">yes</td></tr><tr valign="top" align="left"><td align="left" valign="top"><em>Percentages: </em></td><td align="left" valign="top">N/A</td></tr><tr valign="top" align="left"><td align="left" valign="top"><em>Media: </em></td><td align="left" valign="top">visual</td></tr></tbody></table><p>This property specifies the alignment, in the block-progression-direction, of the areas that are the children of a reference-area. </p><p>Values for the property have the following meaning:</p><dl><dt class="label">auto</dt><dd><p>If the "relative-align" property applies to this formatting object the "relative-align" property is used.

Some values of the property re-determine all three values; other only re-establish the baseline-table font-size. Although this property is not inherited, components of the scaled-baseline-table propagate to child formatting objects if the "auto" value is used on these.

The "writing-mode" property sets both the "inline-progression-direction" and the "block-progression-direction"s. </p><p>The glyph orientation properties, "glyph-orientation-horizontal" and "glyph-orientation-vertical" set the orientation of the glyph relative to the default glyph orientation. The default orientation for glyphs is with the top of the glyph oriented toward the top of the reference area of which the glyph area is a descendant; that is, the glyph orientation is the same as the reference-orientation of the reference area. Glyphs that are oriented at '90' or '-90' degrees from the reference-orientation are said to be <b>rotated glyphs</b>.

For vertical writing-modes, the "direction" property only affects character sequences that generate glyphs that are rotated. </p><p>The following sample fragment of XML is used to illustrate the interaction between the "writing-mode," "direction" and "glyph-orientation-vertical" properties. </p><div class="figure"> <p><img src="GlyphOrientationVerticalandDir-apex-markup.gif" alt="Markup of text in the next figure"><span class="dlink">   <a href="longdesc/GlyphOrientationVerticalandDir-apex-markup.html" title="Long description of illustration 'Markup of text in the next figure'">[D]</a></span></p> <p>Markup of text in the next figure</p> </div><p>In the XML markup of the figure above, the characters are represented by their presentation form (and not their Unicode code points). The order in which the characters are depicted is their storage order. The Hebrew characters in the third line are (from left to right) the first four letters of the Hebrew alphabet: aleph, beth, gimel and daleth. The generic identifiers in the XML markup are arbitrary, but are intended to suggest a sequence of text with two embedded text spans. </p><p>The following figure shows the effect of specifying an assortment of values for the "direction" and "glyph-orientation-vertical" properties that are specified on the three elements in the above XML fragment. In all cases, the "writing-mode" is "tb-rl". And in all cases the Unicode BIDI algorithm <a href="#UNICODE-TR9">[UNICODE UAX #9]</a> is applied to the characters that are the children or descendants of the <t> element, sometimes with explicit directional markup in terms of the "direction" property and other times using the intrinsic direction properties of the underlying characters. The Unicode BIDI algorithm is applied as the last step of refinement (see <a href="#refinement"><b>5 Property Refinement / Resolution</b></a>) and before mapping the characters to glyphs and applying any rotation due to a glyph-orientation value. </p><p>The figure shows seven possible presentations of the sample XML fragment, one with all glyphs having a vertical orientation and six with various combinations of a perpendicular glyph-orientation and direction. In the figure, the correct reading order of the glyphs (left-to-right for the Latin and right-to-left for the Hebrew sub-sequences) is shown by the (red) arrow that is placed on the alphabetic baseline under the glyphs. </p><p>The six combinations of the "direction" and "glyph-orientation-vertical" properties that generated cases (2) through (7) have the property that they preserve the correct reading order when the glyphs are viewed upright. For some of the cases, it is necessary to turn the page one way to view the glyphs of one language and the opposite way to view the glyphs of the other language in an upright position. The reading order is preserved by combining a visual re-ordering of the glyphs using the Unicode BIDI algorithm with a glyph-orientation that ensures the proper reading order for the ordering of the glyphs that results from the Unicode BIDI algorithm. Sometimes it is necessary to explicitly specify the "direction" property to force the desired visual ordering of the glyphs. </p><p>The property specifications that yield the six presentations are given in the table that follows the figure. </p><div class="figure"> <p><img src="GlyphOrientationVerticalandDir-apex-AllVariants.gif" alt="Achievable rotations of Bidi text"><span class="dlink">   <a href="longdesc/GlyphOrientationVerticalandDir-apex-AllVariants.html" title="Long description of illustration 'Achievable rotations of Bidi text'">[D]</a></span></p> <p>Achievable rotations of Bidi text</p> </div><table border="1" cellpadding="2" cellspacing="0"><caption>Table: Properties that produce the above figure</caption><thead valign="top" align="left"><tr valign="top" align="left"><td align="center" valign="middle">Elements/ Cases</td><td align="center" valign="middle"><t></td><td align="center" valign="middle"><t-s1></td><td align="center" valign="middle"><t-s2></td></tr></thead><tbody valign="top" align="left"><tr valign="top" align="left"><td align="center" valign="middle"><p>(2)</p></td><td valign="top" align="left">writing-mode: tb-rl <p>glyph-orientation-vertical: 0</p></td><td valign="top" align="left">glyph-orientation-vertical: 90</td><td valign="top" align="left">glyph-orientation-vertical: 90</td></tr><tr valign="top" align="left"><td align="center" valign="middle"><p>(3)</p></td><td valign="top" align="left">writing-mode: tb-rl <p>glyph-orientation-vertical: 0</p></td><td valign="top" align="left">glyph-orientation-vertical: 90</td><td valign="top" align="left">glyph-orientation-vertical: -90 <p>unicode-bidi: bidi-override</p> <p>direction: ltr</p> </td></tr><tr valign="top" align="left"><td align="center" valign="middle"><p>(4)</p></td><td valign="top" align="left">writing-mode: tb-rl <p>glyph-orientation-vertical: 0</p></td><td valign="top" align="left">glyph-orientation-vertical: -90 <p>unicode-bidi: bidi-override</p> <p>direction: rtl</p></td><td valign="top" align="left">glyph-orientation-vertical: -90 <p>unicode-bidi: bidi-override</p> <p>direction: ltr</p> </td></tr><tr valign="top" align="left"><td align="center" valign="middle"><p>(5)</p></td><td valign="top" align="left">writing-mode: tb-rl <p>glyph-orientation-vertical: 0</p> <p>direction: rtl</p></td><td valign="top" align="left">glyph-orientation-vertical: -90 <p>unicode-bidi: bidi-override</p></td><td valign="top" align="left">glyph-orientation-vertical: 90</td></tr><tr valign="top" align="left"><td align="center" valign="middle"><p>(6)</p></td><td valign="top" align="left">writing-mode: tb-rl <p>glyph-orientation-vertical: 0</p> <p>direction: rtl</p></td><td valign="top" align="left">glyph-orientation-vertical: -90 <p>unicode-bidi: bidi-override</p></td><td valign="top" align="left">glyph-orientation-vertical: -90 <p>unicode-bidi: bidi-override</p> <p>direction: ltr</p></td></tr><tr valign="top" align="left"><td align="center" valign="middle"><p>(7)</p></td><td valign="top" align="left">writing-mode: tb-rl <p>glyph-orientation-vertical: 0</p> <p>direction: rtl</p></td><td valign="top" align="left">glyph-orientation-vertical: 90 <p>unicode-bidi: embed</p> <p>direction: ltr</p></td><td valign="top" align="left">glyph-orientation-vertical: 90</td></tr></tbody></table><div class="note"><p class="prefix"><b>Note:</b></p><ol class="enumar"><li><p>Case (1) has no rotated text. This can occur either because "glyph-orientation-vertical" is set to "0" or because it is set to "auto" and all the characters in the string are the full width variants of the characters. If the orientation of the all glyphs is vertical, then there is no re-ordering of characters. If the "writing-mode" is set to "tb-lr" or "tb-rl" then the "direction" is set to "ltr" and correspondingly, a "writing-mode" set of "bt-lr" or "bt-rl" sets the "direction" to "rtl". Therefore, it is only necessary to explicitly set the "direction" property when it would be different than that set by setting the "writing-mode"; for example, cases (5) through (7).</p></li><li><p>Case (2) can either have the explicit property settings shown in the table or the "glyph-orientation-vertical" property on the <t> element can have the value "auto" and the English and Hebrew characters can be half-width characters. (Of course, there are not any half-width Hebrew characters in real Unicode.) In this case, the re-ordering of characters comes from the bi-directional character types that are assigned to each Unicode character: the Roman characters have type "L" for left to right and the Hebrew characters have type "R" for right to left.</p></li><li><p>Cases (5) through (7) all explicitly set the "direction" property to "rtl". This sets the paragraph embedding level for the Unicode BIDI algorithm to be right to left. Even though the "direction" property is set to "rtl", the ideographic glyphs are not re-ordered because their orientation is not perpendicular to the dominant-baseline.</p></li><li><p>In cases (5) and (6) for the <t-s1> element, the "unicode-bidi" property is set to override even though there is no explicit specification for the "direction" property. The inherited value of the "direction" property (which is "rtl" in this case) is used.</p></li><li><p>In case (7) for the <t-s1> element, the "unicode-bidi" property is set to "embed". It is not necessary to use "bidi-override" because the bi-directional character type for the content of <t-s1> is already "L". (Using the value "bidi-override" would have the same effect as the "embed", however.) The embed resets the embedding level of the content of the <t-s1> to be left to right. Even the "embed" (and the specific setting of the "unicode-bidi" property) is not needed because the bi-directional character type, "L" of the English characters is sufficient to raise the embedding level and cause them to be ordered left to right. Setting the "direction" property to "ltr" is needed if the "unicode-bidi" property is other than "normal" because the inherited value of "direction" is "rtl".</p></li></ol></div><p>If paired punctuation characters, such as parentheses, had been included in one of the text spans, then these characters may need to be "mirrored" as described in the Unicode BIDI algorithm. Mirroring a character means reversing the direction the character faces; for example, mirroring a left parenthesis makes it into a right parenthesis. This insures that the mirrored characters always face the text they surround. </p><p>If the "glyph-orientation" of the characters to which the glyphs correspond is "90" and the embedding level in which the characters lie is odd, then the paired glyphs need to be mirrored. Alternatively, if the "glyph-orientation" of the characters to which the glyphs correspond is "-90" and the embedding level in which the characters lie is even, then the paired glyphs need to be mirrored. In the example above, parentheses that surround the Latin text would not be mirrored in cases (2), (3) and (7), but would need to be mirrored in cases (4) through (6). Conversely, parentheses that surround the Hebrew text would not be mirrored in cases (4) through (6), but would need to be mirrored in cases (2), (3), and (7). </p><p>Within a string of vertical text, when the value of the "glyph-orientation-vertical" property is "90", then each affected glyph is rotated 90 degrees clockwise. This rotation changes the way the rotated glyph is aligned. The horizontal alignment-point of the rotated glyph is aligned with the appropriate baseline from the vertical baseline-table. The appropriate baseline is the baseline identified by the "alignment-baseline" property of the character(s) that generate the glyph area. For example, if the "alignment-baseline" property is not explicitly specified, Latin glyphs are aligned to the (vertical) "alphabetic" baseline and some Indic glyphs are aligned to the (vertical) "hanging" baseline. </p><div class="note"><p class="prefix"><b>Note:</b></p><p>If a glyph, such as a ligature or syllabic glyph, is generated from more than one character, then all those characters must have the same value for the "alignment-baseline" property. </p></div><p>The positions of the (vertical) baselines are chosen to insure that the rotated glyphs will not protrude too far (if at all) outside the line area for the vertical line when the "line-stacking-strategy" property has the value "line-height" or "font-height". In this case, we will say the rotated text is <b>well aligned</b> in the vertical line area. </p><p>To preserve the property that rotated text in a vertical line is well aligned when the "glyph-orientation-vertical" property value is "-90", the vertical baseline-table must be <b>reflected</b> before the rotated text is aligned. Let C be the value of the offset to the "central" baseline in the baseline-table. A baseline-table is reflected by negating every offset in the baseline table (where negating "-N" yields "N") and adding 2 times C to each of the negated offsets. The "central" baseline is defined in <a href="#area-alignment"><b>7.14 Area Alignment Properties</b></a>. </p><p>This action is called "reflecting" because the offset from the original dominant baseline to any baseline in the reflected baseline-table places that baseline on the opposite side of the "central" baseline and the distance from the "central" baseline to that baseline is the same as was from the "central" baseline to that baseline in its original (un-reflected) position. In short, the positions of the baselines are reflected across the "central" baseline. </p><div class="note"><p class="prefix"><b>Note:</b></p><p>If <var>X</var> is the offset of baseline X and <var>C</var> is the offset of the "central" baseline, then <var>-X+2*C = C+(C-X) </var>. <var>C+(C-X) </var> is the offset of the "central" baseline plus the distance between the "central" baseline and baseline X, the baseline being reflected.</p></div><p>Reflecting is necessary, because both the "alphabetic" and the "hanging" baselines are near the outer edges of the vertical line area. If the glyph were simply rotated 180 degrees, then it would stick way out of the intended line area. This is prevented by reflecting the baselines for glyphs that are perpendicular to the dominant baseline and that are rotated 180 degrees from the direction for which that baseline was intended. This last statement applies as much to horizontal baselines as it does to vertical baselines. </p><div class="figure"> <p><img src="Rotations-Combo-HorizNVert-wX.gif" alt="Mixed glyph rotations and writing modes"><span class="dlink">   <a href="longdesc/Rotations-Combo-HorizNVert-wX.html" title="Long description of illustration 'Mixed glyph rotations and writing modes'">[D]</a></span></p> <p> The figure illustrates the positioning of rotated and inverted glyphs in both vertical and horizontal writing-modes. The three examples show first some glyphs typical of the writing mode and then some atypical glyphs in each of the possible orientations, 0, 90, 180 and -90 degrees, in that order. The alignment-point for each glyph is shown as a small "x" whose center is at the alignment-point. </p> <p> Example 1 shows the "tb-rl" vertical writing-mode. It has the ideographic glyph for "country" as its normal glyph and the two letters sequence, "Ap" as the glyphs that are rotated. Note that in the default orientation (0 degrees) and in the inverted orientation, the full width Latin glyphs are used; in the two other orientations, the proportional Latin glyphs are used. There is a small amount of white space between the proportional and the full width Latin glyphs. The dominant baseline is the "central" baseline which is shown in blue. The reflected baseline table is shown for the last (-90 degree) rotation. Note that the position of the "central" baseline does not change when the baseline table is reflected. For the inverted glyphs and the glyphs with a -90 degree rotation, the start-edge of the rotated glyph is on the opposite side from where it is in the un-rotated glyph; hence, the alignment-point on that start edge is not on the edge where the font tables normally place it. </p> <p> Examples 2 and 3 show the "lr-tb" horizontal writing-mode. They have the Latin glyph sequence, "Ap" as their normal glyphs. Example 2 rotates the syllabic Gurmukhi glyph for "ji" and example 3 rotates the ideographic glyph for "country". In example 2, the whole syllabic glyph is rotated as in indivisible unit. For the 90 and -90 degree rotations, the vertical alignment-point, aligning to the "central" baseline, is used in both Examples. Similarly, for the inverted glyph, the baseline table is reflected. For the glyphs with a 90 degree rotation and the inverted glyphs, the start-edge of the rotated glyph is on the opposite side from where it is in the un-rotated glyph; hence, the alignment-point on that start edge is not on the edge where the font tables normally place it. </p> </div><div class="div3"> <h4><a name="direction" id="direction"></a>7.29.1 "direction"</h4><div class="css-cited-medium"><p>CSS2 Definition: </p> <table border="0" class="prop-summary"><tbody valign="top" align="left"><tr valign="top" align="left"><td align="left" valign="top"><em>Value: </em></td><td align="left" valign="top">ltr | rtl | inherit</td></tr><tr valign="top" align="left"><td align="left" valign="top"><em>Initial: </em></td><td align="left" valign="top">ltr</td></tr><tr valign="top" align="left"><td align="left" valign="top"><em>Inherited: </em></td><td align="left" valign="top">yes</td></tr><tr valign="top" align="left"><td align="left" valign="top"><em>Percentages: </em></td><td align="left" valign="top">N/A</td></tr><tr valign="top" align="left"><td align="left" valign="top"><em>Media: </em></td><td align="left" valign="top">visual</td></tr></tbody></table> <p>CSS2 Reference: <a href="https://www.w3.org/TR/REC-CSS2/visuren.html#propdef-direction"> "direction" property </a><br>http://www.w3.org/TR/REC-CSS2/visuren.html#propdef-direction</p> <p>This property specifies the base writing direction of blocks and the direction of embeddings and overrides (see <a href="#UNICODE-TR9">[UNICODE UAX #9]</a>) for the Unicode BIDI algorithm.

The syntax of this property is based on a traditional typographical shorthand notation to set multiple properties related to fonts.</p> <p>All font-related properties are first reset to their initial values, including those listed in the preceding paragraph plus "font-stretch" and "font-size-adjust". Then, those properties that are given explicit values in the "font" shorthand are set to those values. For a definition of allowed and initial values, see the previously defined properties. For reasons of backward compatibility, it is not possible to set "font-stretch" and "font-size-adjust" to other than their initial values using the "font" shorthand property; instead, set the individual properties.</p> <p>The following [first six] values refer to system fonts:</p><dl><dt class="label">caption</dt><dd><p>The font used for captioned controls (e.g., buttons, drop-downs, etc.).</p></dd><dt class="label">icon</dt><dd><p>The font used to label icons.</p></dd><dt class="label">menu</dt><dd><p>The font used in menus (e.g., dropdown menus and menu lists).</p></dd><dt class="label">message-box</dt><dd><p>The font used in dialog boxes.</p></dd><dt class="label">small-caption</dt><dd><p>The font used for labeling small controls.</p></dd><dt class="label">status-bar</dt><dd><p>The font used in window status bars.</p></dd></dl> <p>System fonts may only be set as a whole; that is, the "font-family", "size", "weight", "style", etc. are all set at the same time. These values may then be altered individually if desired. If no font with the indicated characteristics exists on a given platform, the user agent should either intelligently substitute (e.g., a smaller version of the "caption" font might be used for the "small-caption" font), or substitute a user agent default font. As for regular fonts, if, for a system font, any of the individual properties are not part of the operating system's available user preferences, those properties should be set to their initial values.</p> <p>That is why this property is "almost" a shorthand property: system fonts can only be specified with this property, not with "font-family" itself, so "font" allows authors to do more than the sum of its sub-properties. However, the individual properties such as "font-weight" are still given values taken from the system font, which can be independently varied.</p></div><p><em>XSL modifications to the CSS definition:</em></p><p>In XSL the "font" property is a pure shorthand property. System font characteristics, such as font-family, and font-size, may be obtained by the use of the "system-font" function in the expression language.</p></div><div class="div3"> <h4><a name="margin" id="margin"></a>7.31.14 "margin"</h4><div class="css-cited-medium"><p>CSS2 Definition: </p> <table border="0" class="prop-summary"><tbody valign="top" align="left"><tr valign="top" align="left"><td align="left" valign="top"><em>Value: </em></td><td align="left" valign="top"><margin-width>{1,4} | inherit </td></tr><tr valign="top" align="left"><td align="left" valign="top"><em>Initial: </em></td><td align="left" valign="top">not defined for shorthand properties </td></tr><tr valign="top" align="left"><td align="left" valign="top"><em>Inherited: </em></td><td align="left" valign="top">no</td></tr><tr valign="top" align="left"><td align="left" valign="top"><em>Percentages: </em></td><td align="left" valign="top">refer to width of containing block</td></tr><tr valign="top" align="left"><td align="left" valign="top"><em>Media: </em></td><td align="left" valign="top">visual</td></tr></tbody></table> <p>CSS2 Reference: <a href="https://www.w3.org/TR/REC-CSS2/box.html#propdef-margin"> "margin" property </a><br>http://www.w3.org/TR/REC-CSS2/box.html#propdef-margin</p> <p>A shorthand property for setting margin-top, margin-right, margin-bottom, and margin-left of a block-area or inline-area.</p> <p>If there is only one value, it applies to all sides.

For instance, an author may want a box to remain at the top the viewport on the screen, but not at the top of each printed page.</p></dd></dl> <p>Specifies the positioning scheme to be used.</p></div><p><em>XSL modifications to the CSS definition:</em></p><p>The CSS property shall be treated as a shorthand by XSL and maps as follows:</p><dl><dt class="label">static</dt><dd><p>relative-position="static"</p><p>absolute-position="auto"</p></dd><dt class="label">relative</dt><dd><p>relative-position="relative"</p><p>absolute-position="auto"</p></dd><dt class="label">absolute</dt><dd><p>relative-position="static"</p><p>absolute-position="absolute"</p></dd><dt class="label">fixed</dt><dd><p>relative-position="static"</p><p>absolute-position="fixed"</p></dd></dl></div><div class="div3"> <h4><a name="size" id="size"></a>7.31.21 "size"</h4><div class="css-cited-medium"><p>CSS2 Definition: </p> <table border="0" class="prop-summary"><tbody valign="top" align="left"><tr valign="top" align="left"><td align="left" valign="top"><em>Value: </em></td><td align="left" valign="top"><length>{1,2} | auto | landscape | portrait | inherit</td></tr><tr valign="top" align="left"><td align="left" valign="top"><em>Initial: </em></td><td align="left" valign="top">auto</td></tr><tr valign="top" align="left"><td align="left" valign="top"><em>Inherited: </em></td><td align="left" valign="top">N/A [XSL:no, is optional]</td></tr><tr valign="top" align="left"><td align="left" valign="top"><em>Percentages: </em></td><td align="left" valign="top">N/A</td></tr><tr valign="top" align="left"><td align="left" valign="top"><em>Media: </em></td><td align="left" valign="top">visual</td></tr></tbody></table> <p>CSS2 Reference: <a href="https://www.w3.org/TR/REC-CSS2/page.html#propdef-size"> "size" property </a><br>http://www.w3.org/TR/REC-CSS2/page.html#propdef-size</p> <p>This property specifies the size and orientation of a page box. </p> <p>The size of a page box may either be "absolute" (fixed size) or "relative" (scalable, i.e., fitting available sheet sizes).

functionality has been added to support:</p><ul><li><p>Change marks.</p></li><li><p>"Back of the book" index.</p></li><li><p>Bookmarks.</p></li><li><p>"Markers" in tables to support e.g. partial sums.</p></li><li><p>A new fo:page-number-citation-last.</p></li><li><p>Multiple flows.</p></li><li><p>A new fo:page-sequence-wrapper.</p></li></ul></li><li><p>Existing functionality has been extended for:</p><ul><li><p>Conditional graphic scaling.</p></li><li><p>A value of "only" has been added to the page-position property.</p></li><li><p>Values "inside" and "outside" have been added to the clear and float properties.</p></li><li><p>A prefix and suffix may be specified for page numbers. A page number consists of an optional folio-prefix, a folio-number, and an optional folio-suffix. The <b>page-number</b> has been renamed <b>folio-number</b>.</p></li><li><p>The definition of xml:lang has been updated to also refer to "or its successor" of RFC3066 to match the definition in the XML recommendation.</p></li><li><p>The support for XML/XML Names 1.0 and 1.1 has been made consistent with the text in XSLT 1.0 errata.</p></li><li><p><uri-specification> has been modified to support IRIs.</p></li></ul></li><li><p>Miscellaneous changes:</p><ul><li><p>In the content of fo:declarations the fo:color-profile may occur 0 or more times.</p></li><li><p>It has been clarified that absolute-position="absolute" is with respect to the nearest ancestor reference area.</p></li><li><p>Changes have been made to the "id" handling. "id" also applies to fo:root, fo:static-content, fo:flow, fo:footnote-body, fo:footnote, fo:float. "id" has been removed from fo:initial-property-set and fo:multi-properties. </p></li><li><p>"reference-orientation" is no longer an inherited property. </p></li><li><p>It has been clarified that the value of the "reference-orientation" and "writing-mode" are determined by the formatting object that generates the area. A new property value function "from-page-master-region" has been added to permit obtaining the value specified in the page master. </p></li><li><p>The description of <country> in <a href="#country"><b>7.10.1 country</b></a> has been made consistent with its definition in <a href="#datatype"><b>5.11 Property Datatypes</b></a>. </p></li><li><p>Inconsistencies between property value definitions and explanatory text for white space handling has been resolved.</p></li><li><p>An error in the positioning of nested inline areas involving baseline scaling has been corrected.</p></li><li><p>xml:lang, the value has been changed from <country-language> to <language-country> and the implied optionality of the language component removed to correspond with the definition in XML.</p></li><li><p>The value "transparent" has been added to the individual border-"x"-color properties to be consistent with the border-color shorthand.</p></li><li><p>Restrictions, preventing "circularity", on the descendants of fo:marker have been added.</p></li><li><p>A contradiction in the description of fo:initial-property-set between the "Areas" and "Trait Derivation" has been corrected by replacing "fo:wrapper" with "fo:inline" in the "Trait Derivation.</p></li><li><p>An optional recovery action for some errors in tables has been specified.</p></li></ul></li></ul></div><div class="div1"> <h2><a name="d0e45358" id="d0e45358"></a>F Acknowledgements (Non-Normative)</h2><p>This specification was developed and approved for publication by the W3C XSL Working Group (WG).
