Hmm. Since it never caught on, maybe it was partly due to too much complexity, and maybe can invent a simpler solution? I would also be against this idea if the complexity cost would be too high, but I think Tom's foreign key constraint name idea looks fruitful since it's simple and non-invasive. /Joel
