If the relationship is mandatory, I'd use the PK.
As in propagate PK? That does not work in this case because there
can be A rows that do not have any related B rows.
Or did you mean something else?
Yes, that is what I was thinking of. If it is not really a to-
many, why not put the PK of B into A as a FK?
That would just reverse the situation into A <<-> B, no? What I need
to is an enforced A <-> B, and in that B -> A is mandatory, and A ->
B as optional.
