Tried running LM with a model where target entities are using vertical inheritance. The scenario was an lm to the known subclass entity (simpler than lm'ing to the superclass, something that still will not work). So essentially this is an entity with flattened attributes, and the inheritance part is not relevant. What is relevant is that such an entity is stored in 2 tables, and attribute mapping in LM is broken. No reason why we can't support it.
