2.2.2.2 Dispatcher Response Tag Payload
The Dispatcher Response tag payload precedes all DSLR service response tags and payloads returned from DSLR two-way service requests. (DSLR service responses are children of the Dispatcher Response tag.) It includes all information relevant for receiving a response to a specific service request: the type of request being that is made (in this case, the type of request is always a response), and the one-time unique request handle that identifies the specific request to which the response corresponds.
The format for the Dispatcher Response tag payload is as follows:
