W3C Publishes Final Draft of XML Schema Definition Language (XSD) 1.1

The W3C XML Schema Working Group has published the Last Call Working Drafts of "W3C XML Schema Definition Language (XSD) 1.1 Part 1: Structures" and "Part 2: Datatypes." This former specifies the XML Schema Definition Language, which offers facilities for describing the structure and constraining the contents of XML documents, including those which exploit the XML Namespace facility. The schema language, which is itself represented in an XML vocabulary and uses namespaces, substantially reconstructs and considerably extends the capabilities found in XML document type definitions (DTDs). The latter defines facilities for defining datatypes to be used in XML Schemas as well as other XML specifications. The datatype language, which is itself represented in XML, provides a superset of the capabilities found in XML document type definitions (DTDs) for specifying datatypes on elements and attributes. Comments are welcome through 20 February. Learn more about the Extensible Markup Language (XML) Activity. http://www.w3.org/XML/Schema
