Yes and no.  Think about what it means to separate 
the concept of a link from the concept of a locator.

Why was that done?  What is the function of each?  

If a locator can be addressed by multiple links, 
why would one want to do that?

We come back to groves for the same reasons 
the original group ended up there.  Until one has 
a neutral means to describe properties of nodes 
in a sharable descriptive language, it is tough to 
decide when we are talking about the same "type" 
of thing being addressed from multiple contexts.

Len lead me to the idea that maybe we need an hyperlink algebra like the
relational algebra already has. I think that links are intrinsically
linked to an operation. Maybe we can say that a link is an operation -
involving external content - to be performed by an agent. What we need
though, is to explicitly specify these operations. Reading again the
xlink specs it is clear that the intent was for rendetion to human
beings (or ETs :-) ) since several keywords have a rendition
connotation.
