<p class="MsoNormal" style="margin-left:36.0pt">I have done the changes as discussed during the last meeting. I hope that it is now very clear that only LTP red is expected to be used (see 3.5). For BP, I had to switch back to refer to the current (BPv6) CCSDS
Blue Book (I have been too optimistic regarding the publication of the BPv7 version). However, there is a note that the same principles will apply for BPv7 (see 3.4, I think this is the best we currently can do).<o:p></o:p></p>
