Fwiw, this isn't possible in general, since there are non-CSS sources of 
even cascaded data (e.g. HTML presentational hints).  That's not even 
getting into the business of shorthands and what modifying a cascaded 
shorthand value means.

Of course for anything past cascaded values (computed, used, whatever), 
the concept of "originating rule" just makes no sense period.
