Sorry—I had to rewrite a couple of macros to accommodate corrigenda poll conditions. Text 
should have read:
"The CESG poll to approve publication of CCSDS 232.0-B-4 Cor. 1, Technical Corrigendum  to 
CCSDS 232.0-B-4, Issued October 2021, concluded with conditions. . . ."
(But I guess that was clear enough from the message subject.)

Dear Document Rapporteur,
The CESG poll to approve publication of  concluded with conditions. Please negotiate 
disposition of the conditions directly with the AD(s) who voted to approve with conditions and 
CC the Secretariat on all related correspondence.

CESG E-Poll Identifier:  CESG-P-2023-08-002 Approval to publish CCSDS 232.0-B-4 Cor. 1, 
Technical Corrigendum  to CCSDS 232.0-B-4, Issued October 2021
Results of CESG poll beginning 31 August 2023 and ending 14 September 2023:
                 Abstain:  0 (0%)  
 Approve Unconditionally:  5 (83.33%) (Barkley, Fischer, Cola, Aguilar Sanchez, Moury)
 Approve with Conditions:  1 (16.67%) (Shames)
 Disapprove with Comment:  0 (0%)  
CONDITIONS/COMMENTS:
     Peter Shames (Approve with Conditions):  In the edits provided for sec 6.5.3 the following 
text is added:
Whenever retransmission of Type-AD Transfer Frames is required in a series
of frames that originally included both Type-AD and Type-BD frames, then
the SDLS ProcessSecurity Anti-Replay function will reject any retransmitted
frames, if authentication is used, based upon their lower anti-replay sequence
count in comparison to the Type-BD anti-replay sequence count (falsely
labelling them as SDLS security failures). Therefore, mixing Type-AD and
Type-BD frames on the same VC secured by SDLS is generally not advised
unless Type-BD frames are sent only after all Type-AD frames have been
accepted on board.
The wording of the first sentence does not adequately emphasize that this discussion is about 
authentication.  Please reword this sentence as follows:
If authentication is used, and whenever retransmission of Type-AD Transfer Frames is required 
in a series
of frames that originally included both Type-AD and Type-BD frames, then
the SDLS ProcessSecurity Anti-Replay function will reject any retransmitted
frames, based upon their lower anti-replay sequence count in comparison to the Type-BD anti-
replay sequence count (falsely
labelling them as SDLS security failures). 

Total Respondents:  6
