Subject: Re: [xacml] XPath 2.0 support
This seems good to me. The OASIS XACML text already has the references, we just need to update them to the final recommendation. I made this into issue 81 in the issues list. BTW, the current core drafts are based on the OASIS XACML. Is there anything I should bring in from the ITU-T text?
