<span style="font-size:10.0pt;font-family:"sans-serif","serif"">I believe that any CESG member should cast its opinion with her / his CESG hat, No doubt about it.</span>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="color:#0070C0">Yes<o:p></o:p></span></p>

<span style="font-size:10.0pt;font-family:"sans-serif","serif"">In any normal organization participants to IOAG and CCSDS discuss these types of issues internally in advance and prior to the approval of documents at Agency level., such that a consensus can
be reached. The danger is that somebody is overruled or do not say at organization level her ;/ his opinion, and then uses the power of the independent assessor to cast his opinion, This could be a dangerous game, as you have experienced in the past.</span><o:p></o:p></li></ol>
<p class="MsoNormal"><span style="color:#0070C0">There's also a danger to the organization, CCSDS in this case, of being pushed to do something expedient in the short term that has poor long term consequences. It is our role, as CESG members, to try and avoid
such "pitfalls".<o:p></o:p></span></p>
<p class="MsoNormal"><br>
<span style="font-size:10.0pt;font-family:"sans-serif","serif"">In addition, your are always showing the same pattern wrt reviews</span>

<span style="font-size:10.0pt;font-family:"sans-serif","serif"">you are usually waiting until the last instance to deliver "your comments". This will be discussed at the next CESG meeting in relation to the CESG assessment of the quality of recommendations.</span><o:p></o:p></li></ol>
<p class="MsoNormal" style="margin-bottom:12.0pt"><span style="color:#0070C0">Speaking of pitfalls, here is an analogy for you. If you are wandering around in the dark, near such a pitfall, and someone strikes a match at the last minute before you step over
the edge of the precipice, is that more, or less, useful than if no one shines a light of any sort? Or do you blame the person who did shine the light because they didn’t do it sooner? Is everyone who votes "Approve unconditionally" or "Does not affect my
area" shining any light at all on our issues? Is that "feedback" even if it is immediate, particularly useful, or is it just convenient?<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-bottom:12.0pt"><br>
<span style="font-size:10.0pt;font-family:"sans-serif","serif"">Last but not least, please let me have your old mails when complaining about the SC#1 file services.</span>
<br>
<br>
<span style="font-size:10.0pt;font-family:"sans-serif","serif"">If we go back to 2 services (file forward and file return)., will you be happy ? I have already my opinion, but please let us have it.</span>
<br>
<br>
<o:p></o:p></p>
<p class="MsoNormal" style="margin-bottom:12.0pt"><span style="color:#0070C0">I thought that the original file services were an issue too, but I understood the logic of why they were requested. You will find a viable way to provide those defined in the SCCS-ADD,
using the CSTS F-Frame to support it. The logic there remains the same, to define the set of packet, frame, merging, encoding functions once for the ESLT and to re-use them where needed for the "upper level" services like file and DTN. And note, this is
re-use in the "standards plumbing" sense and not the implementation sense, though it should be the case that the one support the other.<o:p></o:p></span></p>
