Please excuse my ignorance of this protocol, but is it different than
what packet-s4406.c dissects?

Yes, this one is very different. This is a very compact format used for transmitting time-critical short X.400 messages (X.420 and STANAG 4406) on low bandwidth channels, such as HF-radios.

A Military Messaging System will convert messages from s4406 to DMP when transmitting through such services.

I have previous added the P_Mul dissector, which is a protocol to transfer X.400 messages in bandwidth constrained and delayed acknowledgement environments :)

All these protocols are described in STANAG 4406 Annex E (DMP is a new one recently added).
