Tom,
I would disagree in some circumstances. But one does need to minimize =
them at all cost. I prefer a before insert/update trigger that does the =
same thing, but that too can become a problem.

Peter,
I totally agree with you. Allowing Fk references from outside of the =
schema
is inviting confusion, duplication and disaster. There is really no =
good
reason for it.

Whoa there everybody!
While the answer is quite correct, of course (I read the FM years ago), =
what
has not been raised is the danger of allowing reference to multiply
unhindered across numerous schemas.
Be very careful if you choose to do this, otherwise, without a little =
care,
you may manage to lock your entire database solid with conflicting FKs!
We did, learned our lesson, and now reference is ONLY permitted within =
the
one corporate schema.
