And that isn't what I was conveying to you. Basically, at what point did
you indicate we where dealing with typed literals? You said A between B
and B between C. Why on earth should I assume A, B, and C are typed
literals? Just because you used the literal 'Between' in some kind of
fuzzy context? (02)
RDF is pretty clear about the semantics for typed literals.

I think we are now talking past ourselves. (04)
If you have some alternative to RDF that works, just point me to it. I
think that's the best use of our respective time at this juncture. (05)
