XPath doesn't, but XSLT does with the document() function.
I must say that having given XQuery the briefest of perusals, I agree with
Evan. Not much there that cannot be handled using XSLT, and a lot of what
would be impossible or ineffiecient for a naive XSLT implementation could
be taken care of by a basic set of optimized XSLT extension elements.
I'm quite sorry I won't be in the UK to attend Evan's session.
