Subject: Re: [xacml] change request: namespaces in xpath expressions
Simon,
You are right. So I agree with your proposal to use xmlns attribute
to indicate the XPath namespace and prefix. I first intended to explicitly
specify
policy-specific information separate from schema-level information but I
think
it might be a minor issue. Since I was a little concerned about the
semantics
duplication particularly of the inheritance through the policy hierarchy,
using
xmlns attribute satisfies this. So please post a change request to the list
to
remove XPathNamespace element and text change in the spec.

Michiharu,
The other use of namespace decl I'm aware of is QName
for the values of xml attributes, such as "xs:string", and XSLT where
namespace prefixes of xpath expressions are expanded when expression is
evaluated.
If you do not want to use xmlns decl, I agree with your proposal:
drop XPathNamespace element from the AttributeSelector and leave
it the PolicyDefaults element only.
