Sorry Tom, I guess I am still a bit confused about how all of this works and if there are any useful ways I can use this feature to enforce the slightly more complicated temporal foreign-key RI.
Does any documentation exist that I could spend some time reading that explains detail the cooperation between triggers on the two tables?
