Chris: I am reluctant to do this. I believe that we currently have two 
major activities in CCSDS - SOIS and Cislunar - that potentially have 
sweeping future ramifications and yet not all Agencies are "onboard". 
[Until recently, SM&C would have been in that category too, though I am 
hopeful that by having taken our time to be fully consultative, we are now 
moving down a track towards consensus.]

I therefore think that we need to look at SOIS as a whole *package*, not as 
individual Books, and that we need to come to a consensus CESG technical 
decision as to how to proceed. After the Area Directors get to look at that 
whole package, and have the opportunity to seek advice from many quarters, 
it may well be that the architecture Green Book will need to be modified. 
That's why I'd like to hold to the process indicated below and issue the 
Green Book [1] + [2-6] + [8-11] + [15-16] for an integrated CESG review.

By the way, the SOIS Green Book and the Cislunar Green Book are both 
"Type-2" in Jean-Luc's terminology, and they both suffer from the same 
problem: they have a strong flight system architectural flavor, yet we 
really don't have an external flight system community to whom we can go to 
confirm that they are acceptable. The IOAG, for instance, really doesn't 
contain much flight system representation.

Best regards
Adrian
