I should add that this also provides context that the MAD layer can use when 
performing DS RMPP.  On the initiator side, DS RMPP would be detected by an RMPP 
request that expected a response.  (This assumes that the response is also 
RMPP.)  On the responder side, DS RMPP is detected when an RMPP response is sent 
in response to an RMPP request.
