Current RECs call for URI/localname pairs as identifiers. They also call
for rawnames as identifiers.

Right. And the methods unrelated to namespaces identify them by rawname.

That's the definition of expanded name. There is also a definition of
"name" which is equivalent to "rawname".

We need both.

XSLT, XPointer, XLink, etc. inherit the behavior from XPath.

I'm not sure what you are suggesting concretely. You and I agree that
most of the current applications allow you to work based on the rawname
or the URI/localname pair. Therefore we need three pieces of
information. How do you suggest we should represent them?
