Some facets are not properties of the topic, but of the indexed resources.

In the card catalogue time, it made sense (to me) to coordinate a topic with a genre (say). But now ? I would prefer 
(at browsing) to select a topic and then the system to offer me a faceted browsing on genres.

For instance, not:

but:

International Congress of Writers for the Defense of Culture$n(1st :$d1935 :$cParis, France)

   Fiction: n1
   History: n2
   etc.: n3
