## Abstract

This document is version 1.1 of XHTML Modularization, 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. This specification is intended for use by language designers as they construct new XHTML Family Markup Languages. This specification does not define the semantics of elements and attributes, only how those elements and attributes are assembled into modules, and from those modules into markup languages. This second version of this specification includes several minor updates to provide clarifications and address errors found in the first version. It also provides an implementation using XML Schemas.

## Status of This Document

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 W3C technical reports index at http://www.w3.org/TR/.

This is the Last Call Working Draft of "XHTML™ Modularization 1.1" for review by members of the W3C and other interested parties in the general public. The last call period ends on 4 August 2006. This document is the merger of the Modularization of XHTML in XML Schema last call draft of 3 October 2003 and the Modularization of XHTML W3C Recommendation of 10 April 2001. The materials from the former are incorporated as appendices into this document (as indicated during that document's last call period), and some clarifications were applied to material from the latter. No major changes in methodology or functionality are included in this version. The HTML Working Group believes that this specification addresses all known issues. Evidence of implementation use of the methodology and schema described herein is documented in the Implementation Report. If this document is approved as a W3C Recommendation, it will supersede the 10 April 2001 version of Modularization of XHTML. The HTML Working Group does not plan to work further on Modularization of XHTML in XML Schema, since it is included herein in its entirety.

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.
