Module message 

Draft-10 control message encoding and decoding.

The wire format is draft-09’s, unchanged: the same 26 message types with the same field lists. Only the section numbering moves, which is why the citations here are one chapter later than draft-09’s.

Filter Type 0x1 is absent, as it is on draft-09 - it was withdrawn there, not here.
