After discussion with the TAG
I've changed my mind... it seems like an OK idea...
XInclude isn't a normal application of XML; it's
a bit of infrastructure, like XML Base, so it
can do things that seem, at a glance, to be
counter to the "Use URIs" principle.

I would like the XInclude spec to cite the
webarch "Use URIs" principle and give a paragraph
of explanation why URIs aren't used in the
usual way.

p.s. was my 10 Nov message received? Anybody home?
