OWL was published by the W3C. I don't see how this is relevant.

Yes it does. It's not an XTM issue, it's an XML issue that has already
been resolved. Read the spec (particularly the examples in section 3):

    http://www.w3.org/TR/xmlbase/

That's the whole point of xml:base. What other purpose could it serve?
XTM is an XML application. We're already using xml:base in applications.
We could decide *not to*, but that'd be foolish. It's there to serve
exactly the purpose of document portability demanded here.

I am having no problems. I am discussing with you design decisions.
You are disagreeing with them. I have done nothing that disagrees
with the recommendations so far as I can see (esp. after I make it
clear that the things labeled "PSIs" are the PSIs, since that is
apparently not clear enough now.
