Market Data Request Reject

A Market Data Request Reject message will be sent in response to a Market Data Request message that cannot be honored due to business or technical reasons. XCDE chose to limit various parameters, such as whether just the top of book and the entire book may be displayed (not specific depths), or only Incremental updates must be used (not full refresh) for example.
