[xacml-comment] Primitive type identifiers in B.4.

Appendix B.4 says that several identifiers are defined in XML Schema and
XQuery.

I know that XML-schema identifiers (like
http://www.w3.org/2001/XMLSchema#string) are
explicitly defined in Section 3 of the XML-Schema specification:
http://www.w3.org/TR/xmlschema-2/#built-in-datatypes

How about the two XQuery-related identifiers?
http://www.w3.org/TR/xquery-operators#dayTimeDuration
http://www.w3.org/TR/xquery-operators#yearMonthDuration
Are these URIs defined in the XQuery specification?
http://www.w3.org/TR/xquery-operators/

If yes, tell me which part of which section defines them?
If no, it should be explicitly said that the XACML specification defines
these two identifiers by itself.
