Working Draft: XML Schema 1.1 Structures

The XML Schema Working Group has released an updated Working Draft of XML Schema 1.1 Part 1: Structures. XML schemas define shared markup vocabularies, the structure of XML documents which use those vocabularies, and provide hooks to associate semantics with them. This draft has changes for XML 1.1, union types, context, canonical forms of values, the Simple Type Definition, and white space handling. Visit the XML home page.
