This working draft defines the mechanism for defining markup language modules that are compatible with the modularization framework used by XHTML. This includes a definition of the way in which an abstract module is specified, the way in which this abstraction is mapped into an XML DTD, and the way in which the resulting DTD module can be combined with other XHTML DTD modules to create new markup languages. In the future, it is expected that instructions will also be provided for mapping the abstract specifications into an XML Schema. Note that the materials in this document were formerly part of the Modularization of XHTML document, but have been separated out for editorial purposes.

Note that, as this is a work in progress, text is frequently added to the document that has not yet been reviewed by the working group. Such text is marked using the class "new", with an appearance like this. Text delimited with class "new" is submitted for consideration by the working group, and necessarily has a lesser status than the text in the remainder of the document. [This technique was agreed at the 5 May 1999 teleconference of the working group.]
