Abstract

This document is the second edition of 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 update includes several minor updates to provide clarifications and address errors found in version 1.1.

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 document is a W3C Proposed Edited Recommendation. If approved, it will supersede the previous edition of XHTML Modularization 1.1. It reflects minor corrections to ensure consistency among various markup languages that rely upon XHTML Modularization. Most significant among these are:

  1. Changing the datatype of the class attribute so that it permits an empty value - historically the class attribute was permitted to be empty.
  2. Moving the name attribute for the form and img elements out of the legacy module and into their base modules - this attribute is required for some scripting constructs.
  3. Changing the datatype for the usemap attribute from IDREF to URIREF - most user agents require that map references be relative URIs that are local to the document.

Due to the nature of XHTML Modularization, the decision to advance to Proposed Edited Recommendation did not involve new implementation information. Previous implementation experience is documented at http://www.w3.org/MarkUp/2008/xhtml-m12n-11-implementation.html. A version that shows the specific changes from that Recommendation is available in diff-marked form. A disposition of comments document is available.
