This specification defines a new XHTML document type that is based
solely upon the module framework defined in the Building XHTML Modules specification with the modules defined in the Modularization of XHTML Working specification. This document type is to serve as the
basis for future extended XHTML family document types, providing
a consistent, forward looking document type (read: not backwards-compatible) that will provide a clean separation from the
deprecated, legacy functionality of HTML 4.0.
