Dear CESG chair and CESG colleagues,

Brigitte and I fully support the proposal by the MOIMS/NAV WG to approve 
the new project for the 5 year revision of the XML Specifications for 
Navigation Data Messages (CCSDS 505.0-B-1) and kindly ask the CCSDS 
Secretariat to establish the required CMC poll. However, before doing this 
we would like to submit a request to the CESG (see below) for approval.

For the 2 prototypes (originally done by NASA and ESA), we would like to 
propose that in this case no prototype is required based on the following 
The revised book will be the result of removing material from the current 
version. In fact, the XML representations of the ADM, ODM and TDM, 
currently in the published blue book, will be migrated to the message 
specific books in the context of their on-going 5-year reviews (e.g. the 
ADM XML will be included in the ADM book revision).
What will be left in the to be approved revised book is the a "Combined 
Instantiation" of navigation data messages (see Section 4.14) along with 
basic sections on XML in general. The Combined Instantiation allows 
merging ODM and/or ADM and/or TDM in a single file.This material will be 
technically unchanged with respect to the currently published book and 
already went through prototyping (see attached NDM/XML PROTOTYPING TEST 
PLAN & REPORT, yellow book)
The above approached is proposed in agreement with the NAV WG chair and 
deputy chair.
There are in general scarce resources in CCSDS, therefore avoiding 
unnecessary work should be welcomed by everyone.

NASA has agreed to take over the book editorship task.

We would appreciate to receive your endorsement for this approach by 

Best regards, 

Brigitte & Mario
