Dear Nestor-san and Nick-san,

In reference to the CMC poll for the following two SOIS documents, I  
would like to have your advice before voting on the CMC poll for 
CMC-P-2015-07-003 and CMC-P-2015-07-004.

- XML SPECIFICATION FOR ELECTRONIC DATA SHEETS FOR ONBOARD 
DEVICES(CCSDS 876.0-R-1)
- SPECIFICATION FOR DICTIONARY OF TERMS FOR ELECTRONIC DATA SHEETS FOR 
ONBOARD COMPONENTS(CCSDS 876.1-R-1)

Concerning the CCSDS 876.1-R-1, JAXA has a question about whether this 
book is Magenta as proposed by CMC poll or Blue as stated by the  
Project Charter and CESG Report. On page ii, statement text for the Blue 
Book remains there. So far as we see the content of this document, we 
consider it a Blue book. While we do not see any particular report in 
the CESG Report about changing from Blue to Magenta, is there any 
discussion in this regard?

On the other hand, title of this document shows “ONBOARD COMPONENTS”, 
while the accompanying document of CCSDS 876.0-R-1 shows “ONBOARD 
DEVICES”. We are not certain whether this difference is intentional. CWE 
Project site introduces this document as Component while the CESG report 
says Device.

Latter subject can be pointed out during the Agency Review, however, we 
would like to know about the former subject for JAXA’s voting on the CMC 
poll.

Regards ---- Shigeta
