<h2><a name="abstract" id="abstract"></a> Abstract</h2>

<p>This document is the second edition of Modularization of XHTML, an abstract modularization of XHTML and implementations of the abstraction using XML Document Type Definitions (DTDs), and XML
Schemas. This modularization provides a means for subsetting and extending XHTML, a feature needed for extending XHTML's reach onto emerging platforms. The second edition of this document provides
several minor updates to provide clarifications and address errors found in the first edition.</p>

<h2><a name="status" id="status"></a> Status of This Document</h2>

<p><em>This section describes the status of this document at the time of its publication. Other documents may supersede this document. A list of current W3C publications and the latest revision of
this technical report can be found in the <a href="http://www.w3.org/TR/">W3C technical reports index</a> at http://www.w3.org/TR/.</em></p>

<p>This document is a working draft, but is nearly complete. It reflects clarifications and corrections as a result of nearly three years of use by the community. It also includes an new
implementation of the abstract modules using XML Schemas. This implementation has gone through the W3C process, including Last Call, and is now integrated here in anticipation of its publication as a
W3C Recommendation. It should in no way be considered stable, and should not be normatively referenced for any purposes whatsoever. It is being published so that the community can review the changes
in anticipation of entering the W3C's Proposed Edited Recommendation process later this year.</p>

<p>Publication as a Working Draft does not imply endorsement by the W3C Membership. This is a draft document and may be updated, replaced or obsoleted by other documents at any time. It is
inappropriate to cite this document as other than work in progress.</p>

<!-- <p>This document has been reviewed by W3C Members and other
interested parties and has been endorsed by the Director as
a W3C Recommendation. It is a stable document and may be used
as reference material or cited as a normative reference from
another document. W3C's role in making the Recommendation is to
draw attention to the specification and to promote its widespread
deployment. This enhances the functionality and interoperability
of the Web.</p>
