Content negotiation ensures that, in the general case, they can't. #foo
means something different (denotes, etc) depending on the content-type
of what you get back.

Also XPointer (I assume) allows you to specify any chunk of xml content; 
having all those refs be eternal would mean you couldn't change the doc
at all.
