    4b: Multi-Party Commerce or OTA (MasterCard)
    In this test case, a travel booking merchant creates a multi-party transaction for the
                cardholder. The merchants participating in the multi-party transaction are required
                to authorize on flights, hotels, and car rentals etc. This test case focuses on what
                the participating merchants are required to send for a successful transaction. Note
                that each participating merchant must send their own CAVV.
