    > Implement horizontal inheritance. This requires:
    > 1. Allow dbEntityName attribute to be null in <obj-entity ...>
    > 2. Modeler changes to allow this to be set. Validation should require that any class set in this way should have at least one subclass.
    > 3. Changes, particularly to SelectQuery, which accomodates this change and returns the appropriate objEntities.
