    No.  Actually, they don't contain objects.  They work by canning a set
of ZCatalog queries.  The object the queries result in after being ANDed
together are the objects that are 'in' the ZTopic, but 'in' only in a
figurative sense.  They can contain more ZTopics, though, and the ZTopics
they contain can serve to refine the searches to provide topical
hierarchies.  It's really neat.
