This is going to be quite a lot of work to do since any automated mechanism in Cayenne or
in the db will work on integer values only.

If you are trying to avoid namespace collisions with some other system, you might be better
off with a compound primary key and managing that by hand.

However any time you have a primary key with meaning is probably a mistake in database design.
You are best trying to avoid this at all costs unless you are constrained by a legacy system
in some way.
