I stand corrected.  That'll teach me to answer from memory instead of
looking it up.  But if so, what's the purpose of a double seal?  Is that

substitution?  If so, why is one seal not enough, as it is for meat, fish,
etc?

                        exercise his rights. The right's existence is all
                        the reason he needs.
