Hi Karen,
good that we have consensus.
Dan, Guha: I think the issue of whether multi-type entities should be solved
a) at markup time or
b) in the vocabulary
is of generic relevance - do you have an opinion on that?
I think that for types that are not disjoint but also only loosely related (like an AudioBook used as a Product), it is much cleaner and flexible to recommend using both types at markup time.
This also decouples the evolution of such needs / use cases from the evolution of the schema.org spec - site owners do not have to wait for an update to schema.org, and search engines can learn from the appearance of new patterns.
