Submission request to W3C (W3C Staff Comment)


This document proposes Document Definition Markup Language (DDML), a schema language for XML documents. DDML encodes the logical (as opposed to physical) content of DTDs in an XML document. This allows schema information to be explored and used with widely available XML tools.

DDML is deliberately simple, providing an initial base for implementations. While introducing as few complicating factors as possible, DDML has been designed with future extensions, such as data typing and schema reuse, in mind.

DDML is a cooperative effort of members of the XML-Dev mailing list. For a complete list of contributors, see Appendix E, "Contributors". Historical information regarding the development of DDML is available at http://purl.oclc.org/NET/ddml.
