If you don't have a bidirectional references from B back to A, then it
could be referenced by many As so how would that factor in. Perhaps
this ought to be a constraint on A itself...

Maybe you want the reference to have an EOpposite. I.e., B would have a
reference back to A and those two references would have each other as
opposites (as in the Library's Writer/Book example).
