I think this is how authority generally works in practice, from  
external references.

Right, not every fragment will point back to the source.  I don't  
think we can solve that problem without assuming pointers where none  
were intended, which would cause a much larger problem.

So if I point my hCard to my employer's website, where they have an  
hCard for the organization, my hCard is then replaced by my  
employer's?  I don't think we can safely expand the meaning of "url"  
like that.  Right now, it only suggests some vague association  
between the object of the hCard (e.g. me), and the destination (e.g.  
my employer's website).  Acting as a pointer to a more authoritative  
hCard is a more specific meaning, and would invalidate a large number  
of already-published hCards.
