Working Drafts: XML Schema 1.1

The XML Schema Working Group has released updated Working Drafts of XML Schema 1.1: Part 1: Structures and Part 2: Datatypes. Please see the status section of each document for changes since the First Public Working Drafts and from the XML Schema 1.0 language. XML schemas define shared markup vocabularies, the structure of XML documents which use those vocabularies, and provide hooks to associate semantics with them. Visit the XML home page.
