reference and namespace for XML schema 1.1 datatypes

If we refer to XML Schema 1.1 Datatypes, I assume we shall use:

[XML-SCHEMA2]
     W3C XML Schema Definition Language (XSD) 1.1 Part 2: Datatypes, D. 
Peterson, S. Gao, A. Malhotra, C. M. Sperberg-McQueen, H. S. Thompson 
(Editors), W3C Working Draft, World Wide Web Consortium, 30 January 
2009, . Latest version available at http://www.w3.org/TR/xmlschema11-2/.

- How is the policy here? Do we depend on them getting to rec before we 
can get to rec?
- I assume the namespaces for XML Schema datatypes, i.e.
      http://www.w3.org/2001/XMLSchema#
  just remains the same (hopefully, anything else would mean trouble),
  right?

thanks for clarification,
Axel
