                Definition: Flag indicating if the Business Message exchanged between the MessagingEndpoints is possibly a duplicate. If the receiving MessagingEndpoint did not receive the original, then this Business Message should be processed as if it were the original. If the receiving MessagingEndpoint did receive the original, then it should perform necessary actions to avoid processing this Business Message again. This will guarantee business idempotent behaviour. NOTE: this is named "PossResend" in FIX - this is an application level resend not a network level retransmission
