  ## RawCmd
  -**Reason for Deprecation:** Message is ill-defined (doesn't specify
  -where the data should go, assumes all devices have one endpoint which
  -is very not true), was never actually implemented in any reference
  -implemenation. Being superceded by RawDataCmd and RawDataReading. As
  -the message was never in any protocol implementation, it can safely be
  -ignored when implementing new servers, but should also not be used to
  -name new messages (hence RawDataCmd and RawDataReading).
