You will use inheritance, I hope. Not just build everything from scratch?

We already have a simple example. A ConeSearchResponse inherits from the
VOTable model. It is a VOTable that must have RA, Dec, and ID attributes.

We can also inherit curatedTable from Table by adding the VOResource
curation information.

Please tell me you are not going to rebuild all this stuff that we already
have....?
