That will be more complex than Hytime, Michael.

You have to decide the status of linktypes, that is, 
are they first class objects?  Then you have a basis 
for understanding their role in the object framework. 
The XML follows.  The decision to be made is what 
a link declares about its targets.   This is a 
well-trodden path that is a bit overgrown with 
weeds at the moment.

That's what an ontology does, I think.  Not link information, but
relationship information, which
could be used by an application to follow links, or generate XQuery,
DOM, XSLT, or whatever to leverage the relationship information.  Not
that I'm going to channel Ted Nelson and suggest that simple one way
HTML hyperlinks are evil, but I think I can defend the proposition
that in a world where XQuery (or maybe just XPath2, not sure ...) and
OWL exist and are widely supported, XLink doesn't add much if

Agree!  So should that be a core part of some future XML, or a small
supplemental spec on the order XML Base, or what?

So, the "this is a link" namespace or whatever for simple things, and
OWL for the times when you really do need to specify the direction,
type, role, etc. of a relationship, maybe?
