4. The XHTML 2.0 Document Type

This section is normative.

The XHTML 2.0 document type is a fully functional document type with rich semantics. It is a collection of XHTML-conforming modules (many of which are defined in this specification). The Modules and the elements and/or attributes they define are listed here for information purposes, but the definitions in their base documents should be considered authoritative. In the on-line version of this document, the module names in the list below link into the definitions of the modules within the relevant version of the authoritative specification.
