This is largely a matter of personal preference.  It is *precisely* the reason 
I think Topic Maps gets it wrong.  I don't think some global abstraction of a 
"public subject" is any more a trueness of the W3C than their Web page is.  
Therefore, TM introduces a whole level of indirection and complexity for no 
gain whatsoever, IMO.

I've gone back and forth endlessly with TM folks on this and I've concluded 
that liking the subject/occurrence/etc. quiddities is a matter of taste.
