In answering the question, it might help to have information on two background
items.
The first item is the politics of the situation. I gather from Chad Hendren's

Relational Inheritance Thoughts
The most fundamental property of relational inheritance is that it creates
hierarchies of relations that act as composite relations. That is,
relational inheritance produces a tree of relations (presumably tables) that
itself can be treated as a relation. The

themselves. One has to refer to the _per se_ class by referencing an
associated table. While it
