As I already noted
  http://lists.w3.org/Archives/Public/www-rdf-comments/2002OctDec/0282.html
section 3.1 says
 "each .built-in. datatype is also defined in the namespace
  whose URI is http://www.w3.org/2001/XMLSchema-datatypes"

So to identify an XSD datatype you have a namespace URI plus the
datatype name "in the namespace" - a pair of items.  RDF uses
URI-references to identify resources.  Section 3 clearly defines the
URI-reference for the atomic datatypes, which is what existing RDF,
DAML+OIL and soon OWL are using.
