Thanks. It still leaves me puzzled on the question of what if any drawbacks are there of serializing without making an explicit type declaration in the face of use of cnt:chars or its cousins for the other cnt:Class types. In other words, what is gained by seeing the class declaration in the Annotation vs not? What would humans or software do differently if they had no way to determine that the object is a cnt:Class? The main thing that comes to mind is that in dealing with content, applications built with good rdfs support would probably be able to switch just on the cnt:Class subclass, rather than switch on the predicate URI itself. This doesn't seem like a very big advantage, if any.
