<p class="MsoPlainText" style="margin-left:.5in"><span style="font-size:16.0pt">In essence, the condition you have raised is "Have you considered characterizing this as an MB?".

<p class="MsoPlainText" style="margin-left:.5in"><span style="font-size:16.0pt">Based on the specifications you cite, while there may be some case to be made for making this a Magenta Book, I am hoping to convince you that leaving this as a Green Book is the
better course of action.</span><o:p></o:p></p>

<p class="MsoPlainText" style="margin-left:.5in"><span style="font-size:16.0pt">1. This is version 4 of a document that has been a Green Book since 2001. Anyone who might have used this book in the past may not be able to find it if the "color" changes.</span><o:p></o:p></p>
<p class="MsoPlainText" style="margin-left:.5in"><span style="font-size:16.0pt"> </span><o:p></o:p></p>
<p class="MsoPlainText" style="margin-left:.5in"><span style="font-size:16.0pt">2. This version of the document is incredibly overdue. It's a long story that I'll condense considerably... but Version 4 was originally proposed in 2009, took a few wrong turns,
was finally made an official project in 2015 with a target date in October 2017, and then got delayed from there until it was re-assigned to a "can do" Lead Editor. I am concerned that a color change at this point will delay things even further with marginal
benefit.</span><o:p></o:p></p>

<p class="MsoPlainText" style="margin-left:.5in"><span style="font-size:16.0pt">3. Given the emergence of the SANA Registry as a viable resource for CCSDS materials, and the emphasis of this particular Green Book on "Definitions" and "Conventions", the Navigation
Working Group has actually been considering phasing out this book entirely after migrating the bulk of the material to the SANA. While we have not embarked seriously upon this course, we have been considering it since the Fall 2016 Meetings in Rome and have
laid some of the foundations with the registries in <a href="https://sanaregistry.org/r/navigation_standard_normative_annexes">
https://sanaregistry.org/r/navigation_standard_normative_annexes</a> .</span><o:p></o:p></p>

<p class="MsoPlainText" style="margin-left:.5in"><span style="font-size:16.0pt">Therefore, I would like to request that you consider the condition "satisfied" and free up this book for CMC Poll and eventual publication. It represents a substantial improvement
over the current Green Book version 3 published in May 2010.</span><o:p></o:p></p>
