By commit I was thinking of CommitTransactionCommand, which isn't going
to exit a pre-existing transaction block, so I'm not sure that we are
disagreeing.
One interesting point is whether it's possible for one procedure to call
another, and if so what that means for the semantics. Is the inner
procedure allowed to commit a transaction started by the outer one?
