You're going to need to be more specific. I don't

Let's run with that analogy for a minute. If I 
were claiming Lisp and S-exprs were equivalent, 
you could show me some Lisp programs that could 
not be written as S-exprs without also writing an 
S-expr interpreter. I want to see the RDF 
programs that could not equally easily be written 
with plain XML. So far I've only heard it claimed 
that these exist, but I haven't been able to get 
anybody to produce one. In fact, the few cases I 
have looked at deeply turned out to be based on 
plain XML and not RDF at all! If this stuff is 
really practical, it shouldn't be that hard to 
come up with an existence proof.
