In my reading of the Dexter hypertext model, the only deficiency in the 
model that stuck with me (also the only one I spotted)  was the assumption 
that there could be no dangling references.  Even within a single document, 
it can never be assumed that references will never dangle.  If nothing else, 
a stray cosmic ray or neutrino can strike at the wrong place & time and 
temporarily wipe out an existing reference (the hypertext equivalent to "I 
thought I was wrong once; turned out I was right after all..." :)).  URNs 
will be great, but they won't be omnipotent.
