I honestly think this is one of those "how many angels on the head of a 
pin" discussions.  To the great unwashed out there the distinction will 
be lost.  And introducing a new URI scheme seems a heavy weight solution 
for such an esoteric problem.  I sort of like your bnode abstraction 
because it allows the creation of a decent node that I can reference 
throughout a document.  It is way better than the fragment identifier 
approach I was going to take.  I think I will try going that way and see 
where it takes me.
