Use of Xquery with XACML

Dear all,

After looking at the restricted use of Xpath in XACML , i propose the use of 
Xquery , which is much more advanced n have a alots of database SQL like 
features to query to the XML documents, and it is very feasible to use 
Xquery instead of Xpath  for advance Queries in XML.

In this regard , Dear seth , do u have some knwoledge of java libraries 
about Xquery , so that they can be easily embeded into the SUN's 
implemenation ??



with Best regards.
Muhamamd.
