Works for me.  Anybody else?

In BPEL4WS 1.1 for example, the attributes 'queryLanguage' and 'expressionLanguage' of the top level element <process> both use the value "http://www.w3.org/TR/1999/REC-xpath-19991116"; to indicate that the XML query/expression language used in the assignments (data mappings in BPEL) are based on XPath (which is the default). So we might also simply use the spec URI (for XPath 2.0 http://www.w3.org/TR/xpath20) for the namespaceURI, since XPath 2.0 itself only defines 'internal' namespaces for its function and data type identifiers.
