When we get to inheritance, we'd be wise to follow the JPA

for specifying inheritance relationships. Vertical and single-table
is well-defined.

Okay, so consider the request for superRelationship dropped. (See
disclaimer :-) Well that makes it simpler to do all of this ;-)
Hang on... Hibernate, for example, does indeed utilise a
relationship, to my understanding [1], that specifies the nature of
the relationship to the parent, what happens when an object is
deleted and so on. These are characteristics that are encapsulated in
a relationship. This is why the request for defining a
superRelationship in ObjEntity was first made. Perhaps it's an
optional for vertical where in its absence is some implicit strategy.
Thoughts?
