This sort of question is one of the reasons I go to the Extreme Markup
conferences -- there are people there who have been spending a lot of
time thinking about this sort of question.

To some extent this can be hidden behind functions -- I actually think
XQuery has so far failed to address its requirement of supporting
pointers/links, but few othew XML (or even Web) query systems do
better. There isn't consensus on how to represent relationships.
So the difficult part is that you can't write the functions to be
general. One could use RDF schema annotations, I suppose.
I'm rambling, but I think really I'm agreeing with you, and trying to
think about ways to go further.
