That sounds a lot better than links to me; relationship information.
Some apps may want to generate hyperlinks from the combination of
relationships and document(s), others may do other things as Peter
suggests. 

So there are now three things.
doc.xml 
relationships.xml
and 
application.exe which plays with combinations of the above using
some collection of todays tools.

I'd put these into application.exe? I want to show this relationship
in this specific way for that specific purpose? Sort of configuration
information for application.exe?

I like that.

I'll leave that to others :-)
But I do like it 'outside' my xml instance. 
Keeps the xml instance nice and simple? I've only got points (id's?)
and Gavin tells me they could equally well be put in the
relationships.xml document[1]. KISS principle?
  Would that mix nicely with XML-- which steps gracefully
from docHead world to dataHead world? No id/idref pairs?

Or something quite simple and in between until the need for the OWL's
wisdom is perceived?
