Good morning, just a few comments and questions..

1) current 4bits for msgVersion and 4bits for hdrType. With 14 messages and some not implemented (suspend/resume/...) we have little headroom in 4bits of hdrType.  Shall I make the msgVersion 3bits and the hdrType 5bits?

2) the smallest interleaved FEC encoded msg is 30 bytes. With 8 bytes of data: a msgSpec, using RS(15,9) with 4bit symbols, and 4 symbol block interleaving, the smallest on the wire is 30 bytes. Without FEC enabled is it 8 bytes.

3) when run to the end of hdrType room, we can add a jump tag and have a second hdrType field as the 9th byte.

Again, the valid document  link is:

Thank you,

Excuse me for failing to complete this email./ I wanted to ask for feedback on these structures, especially the header specification word structure. So these fields make sense?

thank you,
