In Scenario COB8, should an acknowledgement message be sent from the dealer to venue between steps C (partial fill from venue to dealer) and D (order amend from dealer to venue)?

By default, no new message will be specified, because the venue is considered to hold the master state of the order, and therefore confirmation from dealer to venue is redundant.
