On the other hand, I am not sure I grok when I would use a fetched property, as opposed to a stored fetch request. Is there an implicit "must be in a relatioship with the entity that the fetched property is a part of" condition on a fetched property, or some such?

Think of how you might represent a smart playlists in iTunes. You could use a fetch request in place of a fetched property, but this requires a different (and "explicit") code structure -- that is, you'll have to retrieve the fetch request from the model then execute it.

Thanks,
