Yeah, I'd followed that down a bit and figured out I just needed to
register the class as a base.  But I also see in the Zope code that
registering a class as a base basically creates a zclass from the
base class and puts that in the zclass base class list (if I'm reading
the code right).  However, in the end it doesn't really matter, as it
lets me do what I want to do.

OK, this makes sense.  I'd rather *not* disable the storage tab, as I
do want someone to be able to override the defaults I'm providing.
