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.

This document has been reviewed by W3C Members, by software developers, and by other W3C groups and interested parties, and is endorsed by the Director as a W3C Recommendation.
This document has been produced by the W3C XHTML 2 Working Group as part of the HTML Activity.
For purposes of the W3C Patent Policy, this Superseded Recommendation has the same status as an active Recommendation; it retains licensing commitments and remains available as a reference for old -- and possibly still deployed -- implementations, but is not recommended for future implementation. New implementations should follow the latest version of the HTML specification.
