I think I understand those things (although of course you are free to tell
me I don't). 

Personally, I am ok with a position that allows context of use to affect
what is identified when a reference is made using an identifier.

I think there are folks who want, or believe, that what a URI identifies is
context independent (or the same in all contexts). I thought that there was
a bias toward that POV in webarch. However, on a quick scan of the
"Identification and Resources" section I don't it is stated explicitly. 

If the resource referenced by a URI varies with context of use (which I
think is what you are saying) we should state that very clearly in Web Arch.
