Reviewer: Linda Dunbar Review Date: 2021-07-19 IETF LC End Date: 2021-08-13 IESG Telechat date: Not scheduled for a telechat Summary: This document offers alternate ASN.1 modules that conform to the 2002 version of ASN.1 for Evidence Record Syntax (ERS). Question: Is the Evidence Record Syntax specified in this draft going to obsolete RFC4998? How come the AlgorithmIdentifier in this draft is slightly different from the AlgorithmIdentifier in RFC4998? This draft has: AlgorithmIdentifier{}, DIGEST-ALGORITHM FROM AlgorithmInformation-2009 -- in [RFC5912] { iso(1) identified-organization(3) dod(6) internet(1) security(5) mechanisms(5) pkix(7) id-mod(0) id-mod-algorithmInformation-02(58) } RFC4998 has: AlgorithmIdentifier FROM PKIX1Explicit88 { iso(1) identified-organization(3) dod(6) internet(1) security(5) mechanisms(5) pkix(7) mod(0) pkix1-explicit(18) } RFC4998's pkix1-explicit(18) is not present in this draft. Is it intended? Best Regards, Linda Dunbar
