It would be nice to have the ability to not persist embedded documents if they are "empty", similar to how nullable=false works for null properties. Thoughts?
What is that embedded object contains a non-nullable field? One mapping will definitely have to override the other.
hmm yes, I suppose you'd have to iterate into each embedded document and check the nullable mapping...or let the embedded object's do-not-persist-if-empty mapping override it.... Which could be confusing for users, but could be a nice NoSQL-like feature to have...
