Hi Peter, hi all, ok. You are right, I was not aware that they are 100% interoperable. "CryptographicMessageSyntax2004 -- FROM [RFC3852]" Interoperable with "ContentInfo FROM PKCS-7" "AlgorithmIdentifier FROM PKIX1Explicit88" Interoperable with "AlgorithmIdentifier FROM AuthenticationFramework" Where I am unsure is whether to A) list the current (version 09) ASN.1 structure and put the other imports that you propose in the appendix or B) vice versa (i.e. as you proposed below). Is there a strong reason/opinion why we should choose option B?
