Last Call: XML Schema 1.1 Datatypes

The XML Schema Working Group has released a Last Call Working Draft of XML Schema 1.1 Part 2: Datatypes. Comments are welcome through 31 March. XML schemas define shared markup vocabularies, the structure of XML documents which use those vocabularies, and provide hooks to associate semantics with them. With XML Schema Part 2, datatypes may be defined for use in XML schemas as well as other contexts. Visit the XML home page.
