<p>In <a href="/wiki/Computing" title="Computing">computing</a>, the term <b>Extensible Stylesheet Language</b> (<b>XSL</b>) is used to refer to a family of languages used to transform and render <a href="/wiki/XML" title="XML">XML</a> documents. </p><p>Historically, the <a href="/wiki/W3C" class="mw-redirect" title="W3C">W3C</a> XSL Working Group produced a draft specification under the name "XSL", which eventually split into three parts: </p> <ol><li>XSL Transformation (<a href="/wiki/XSLT" title="XSLT">XSLT</a>): an <a href="/wiki/XML" title="XML">XML</a> language for transforming XML documents</li> <li>XSL Formatting Objects (<a href="/wiki/XSL_Formatting_Objects" title="XSL Formatting Objects">XSL-FO</a>): an <a href="/wiki/XML" title="XML">XML</a> language for specifying the visual formatting of an XML document</li> <li>XML Path Language (<a href="/wiki/XPath" title="XPath">XPath</a>): a non-XML language used by XSLT, and also available for use in non-XSLT contexts, for addressing the parts of an XML document.</li></ol> <p>As a result, the term "XSL" is now used with a number of different meanings: </p> <ul><li>Sometimes it refers to <a href="/wiki/XSLT" title="XSLT">XSLT</a>: this usage is best avoided. However, "xsl" is used both as the conventional namespace prefix for the XSLT namespace, and as the conventional filename suffix for files containing XSLT stylesheet modules</li> <li>Sometimes it refers to <a href="/wiki/XSL-FO" class="mw-redirect" title="XSL-FO">XSL-FO</a>: this usage can be justified by the fact that the XSL-FO specification carries the title <i>Extensible Stylesheet Language (XSL)</i>; however, the term XSL-FO is less likely to be misunderstood</li> <li>Sometimes it refers to both languages considered together, or to the working group that developed both languages</li> <li>Sometimes, especially in the Microsoft world, it refers to a now-obsolete variant of XSLT developed and shipped by Microsoft as part of <a href="/wiki/MSXML" title="MSXML">MSXML</a> before the W3C specification was finalized</li></ul> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="History">History</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=XSL&action=edit&section=1" title="Edit section: History"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>XSL began as an attempt to bring the functionality of <a href="/wiki/Document_Style_Semantics_and_Specification_Language" title="Document Style Semantics and Specification Language">DSSSL</a>, particularly in the area of print and high-end <a href="/wiki/Typesetting" title="Typesetting">typesetting</a>, to XML. </p><p>In response to a submission from Arbortext, Inso, and Microsoft,<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> a W3C <a href="/wiki/Working_group" title="Working group">working group</a> on <i>XSL</i> started operating in December 1997, with <a href="/w/index.php?title=Sharon_Adler&action=edit&redlink=1" class="new" title="Sharon Adler (page does not exist)">Sharon Adler</a> and <a href="/w/index.php?title=Steve_Zilles&action=edit&redlink=1" class="new" title="Steve Zilles (page does not exist)">Steve Zilles</a> as co-chairs, with <a href="/wiki/James_Clark_(XML_expert)" class="mw-redirect" title="James Clark (XML expert)">James Clark</a> acting as editor (and unofficially as chief designer), and <a href="/wiki/Chris_Lilley_(W3C)" class="mw-redirect" title="Chris Lilley (W3C)">Chris Lilley</a> as the W3C staff contact.
