Well, yes, it wasn't exactly the point you were making, Sean.  But I see two
subthreads in this thread.  One is the deep issue of representations and
when they are equivalent or otherwise, which gets into the question of what
a URI indicates, as you have said just above.

The other subthread is the practical question of how to distinguish between
various possibilities (some of which are raised by the first subthread),
once we're clear what they are.  Both subthreads seem to get mixed together
easily.  I just wanted to see if there is some agreement on the second
subthread, which I take to be easier to think about.  If so, it might be
easier to work out the first one.
