refers only to USLP. Similarly, the description provided in Annex 2 points only to USLP and generically about space-to-space and ground-to-space links. I’d suggest to explicitly mention AOS too.<o:p></o:p></span></p>

adding a chapter about specifying the codes (as I read from the description)? As such I understand, that new codes other than those of the ETSI DVB-S2 specification will be considered in this new chapter. Then, I also read that this new chapter will also specify
the space link protocols. What does it mean exactly? Apparently I see something more than just “editing work”, probably requiring validation through interoperability testing (i.e. with the typical 2 prototypes). Why isn’t it the case?<o:p></o:p></span></p>
