You and Eve seem to be taking the most trivial use of RDF and generalizing
it to death.

Of course simple directed arcs can be represented as XLinks, but how do
you conveniently deal with such useful RDF constructs as

Classes/Schema Constraints
Anonymous resource handling
RDF XML serialization flexibility

And such not-so-useful constructs as

about-each and about-each-prefix
RDF XML serialization flexibility ;-)

Disagree.  I have spent a fair amount of time working over XTM, and I'm
convinced, for purely technical reasons (because I could use Topic Maps
with no political problems) that XTM is problematic for my needs, though I
can see where it is useful.

The key thing is that RDF is at a lower level than XTM, and I think a
merger would be a serious confusion of paradigms.
