EJB 1.1 does not specify relationships among entities. So the behavior is currently
undefined. We are considering adding support for relationships in 2.0.
Note that if you have an aggregation relationship that is a composite aggregation,
you may want to consider implementing the dependent object not as an entity bean,
but simply as a Java class.

IMHO, I think we need a clarification on this behavior from Vlada. It seems
likely that EJB vendors are going to go in different directions on this one.
The container's behavior when referenced beans are deleted or when containing
beans are deleted (cascading deletes) should be specified.
