It's not clear that checking uniqueness is desirable. It makes sense
for validating parsers, but as a run time linking facility which 
appears to be the main use case here, just taking the first available
node with that identifier seems preferable. (This is like the xpath
id() function, which does not require unique ids.)
if you connect to http:ksvdbsldbsl#foo and ksvdbsldbsl has two nodes
labeled "foo" then going to the first of them is (or might be)
preferable to being given an error message.
