 *<B>Assertion ID:</B> A6.5-3.
 *<BR>
 *<B>Assertion Description: </B>
Subclasses of such classes that are not persistence-capable,
but have a superclass that is persistence-capable might be persistence-capable.
That is, it is possible for classes in the inheritance hierarchy to be
alternately persistence-capable and not persistence-capable.
