Errata Item 3: Namespace Context for XPath Expressions

The Namespace Context for XPath Expressions errata item on the XACML Wiki (https://wiki.oasis-open.org/xacml/XacmlErrata) states the issue, provides a link to a discussion thread, but doesn't state specifically what needs to change in the XACML v3.0 specification. The note from Erik suggest that XPathExpression is defined in Appendix A.2 and the attribute selector is implicitly defined by the evaluation procedure in section 7.3.7

Requesting a clear indication of what needs to change in the XACML v3.0 specification or agreement that the specification's definitions, as Erik notes, is adequate and no change needs to be made.
