>Regarding your comment:
>
>Gian Paolo Calzolari - Last but not least I 
>think that a feedback effect (e.g. Technical 
>corrigendum) to CCSDS 734.2-B-1 is required for 
>Annex B y=that contains the Convergence Layer Adapters (CLAs).
>Clause in B2.1 states "Compliant implementations 
>shall implement at least one of the CLAs in this 
>section." but, as the (normative) Annex B defines the following 3 CLAs
>- LTP CONVERGENCE LAYER ADAPTER
>- UDP CONVERGENCE LAYER ADAPTER
>- CCSDS ENCAPSULATION SERVICE CONVERGENCE LAYER ADAPTER
>then BSSP would not be not BP compliant.....
>Therefore it looks wise adding there the 
>definition of a TCP CLA and/or stating something 
>in B2.1 that the list of CLAs in Annex B is not exhaustive.
>I also noticed that (normative) section A6 BASIC 
>REQUIREMENTS mentions adapters referring to 
>sections B3.1.2 and B4 but not B5 (i,e. the 
>CCSDS ENCAPSULATION SERVICE CLA defined in B5 
>and the LTP CLA for Unreliable transmission 
>defined in B3.1.3 should be added to the table in A6).
>
>Since that comment really relates to a DTN book, 
>I asked Keith to comment.  Here is his response:
>
>If you ONLY implemented BSSP then it wouldn’t be 
>compliant.  But for a BP-compliant 
>implementation if you implement UDP and BSSP, or 
>LTP and BSSP, you’d be good.  I think you can 
>recommend using BSSP if you like (really, 
>anything since it’s a Green Book) and leave the 
>requirement from the BP Blue Book alone.

>You may want to review the document before we

>everything.  If that is the case, I would just
