FWIW I started at populating the attr release context with the map of requested attributes, perhaps the function to do so could be injected into the appropriate populate action. That function in this case could be injected with the predicate, that's the model I believe.

But I don't really like instantiating the predicate in the view-state. Kinda yuck.

I agree though.
