The purpose of this document type is to serve as the basis for future extended XHTML 'family' document types, and to provide a consistent, forward-looking document type cleanly separated from the deprecated, legacy functionality of HTML 4 [<a href="references.html#ref_html4">HTML4</a>] that was brought forward into the XHTML 1.0 [<a href="references.html#ref_xhtml1">XHTML1</a>] document types. This document type is most similar to XHTML 1.0 Strict, built using XHTML Modules. This means that many facilities available in other XHTML Family document types (e.g., XHTML Frames) are not available in this document type. These other facilities are available through modules defined in XHTML Modularization, and document authors are free to define document types based upon XHTML 1.1 that use these facilities (see [<a href="references.html#ref_xhtml_modularization">XHTMLMOD</a>] for information on creating new document types).</p> <h2 id="status" typeof="bibo:Chapter" about="#status">Status of this document</h2> <p><em>This section describes the status of this document at the time of its publication.
