This sounds a bit as if I might have written it, so let me expand. It's
actually been quite a troublesome area, in sorting out the detailed
semantics of the document-uri() function. 

If you're interested in the subtleties you might like to follow the
discussion at

http://www.w3.org/Bugs/Public/show_bug.cgi?id=3173 

which is not yet resolved, but which I think is heading in the direction of
relaxing the requirement that

doc(document-uri(D)) is D

must always hold.
