<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri">I've just looked over the package. On pg 4 I think we are missing the Registry Management Policy, CCSDS 313.1-Y-1, which was published in June.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri">On pg 12 I do not know what this means:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri">"</span> <span style="font-size:11.0pt;font-family:Calibri">
The grouping of TM, TC and Alert/Event services as M&C seems more logical from an Application Layer viewpoint. The current grouping reflects historical perspectives based on TM/TC protocols."<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri">Are you saying that TM, TC, and Alert should be Application Layer services? Those are link layer, unless you are really meaning the SLE services that deliver these data (and AOS too).
And even if you are meaning SLE, these are really extensions of the link, as named, even if they have their own service interfaces. They are not Application Layer in any usual sense that term is used. To be frank, I do not know why the MOSSG would concern
itself with these services at all, except to just use them as is. Likewise AOS bitstream service.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri">On pg 13, under "interoperability", mention of:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri">"compliance with long‐term digital preservation practices, such as CCSDS standards for OAIS, PAIS"<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri">Is misplaced since these are MB procedures and do not exhibit any properties, nor define any standards, related to interoperability. If they develop some sort of formal specs for data
exchange that would change, but right now this is not accurate.<o:p></o:p></span></p>
