The chances of there ever being an XPointer 2.0 look very dim right 
now. Conformance levels would be a good idea, perhaps.

I must say that much of the size of XPointer is due to unification 
with XPath...

The best argument that I've seen for conformance levels is to make a 
level that would be easy for streaming-only applications -- This 
would include child sequences, ranges and labels, but eliminate 
more-complex navigation that requires an implementor to either keep a 
tree around or do some pretty clever preprocessing on the path.

I could (personally) lose a lot of the navigation features, but 
without ranges, none of the applications that I have for Xpointer 
will be accommodated. Given the number of XPath implementations, 
though, I can't see XPointer as being that hard.

XLink is going to stay listless until there's some version of 
XPointer, that's for sure.
