Not sure about that. We have for example an employee table that is
referenced just about everywhere (e.g. which salesperson is responsible
for this customer, which employee registered for this training course,
which operator filed this incident report, ...). These are all different
apps/schemas referencing this table so I don't see how we can avoid
cross-schema FKs.

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.
