_mandatory_ <del> Reference Claims are components of Reference Values as defined in I-D.ietf-rats-architecture.  [Editor's Note: Definition might become obsolete, if replaced by Reference Values.  Is there a difference between Claims and Values here?  Analogously, why is not named Reference Claims in the RATS arch?] Reference Claims are used to appraise the Claims received from an Attester.  For example, Reference Claims MAY be Reference </del> <ins> Reference Values as defined in I-D.ietf-rats-architecture.  This specific type of Claims is used to appraise Claims incorporated in Evidence.  For example, Reference Values MAY be Reference </ins> Integrity Measurements (RIM) or assertions that are implicitly trusted because they are signed by a trusted authority (see <del> Endorsements in I-D.ietf-rats-architecture).  Reference Claims </del> <ins> Endorsements in I-D.ietf-rats-architecture).  Reference Values </ins> typically represent (trusted) Claim sets about an Attester's intended platform operational state.

text: This is because an Attesting Environment should not be distinguishable and the DAA credential which represents the Attesting Environment is randomised each time it used. Comment > In my understanding, here says that the DAA credential identities the Attesting Environment. Compared with the description in the "Attester Identity" part, what does the DAA credential represent actually? Reference Claims ('refClaims') mandatory Reference Claims are components of Reference Values as defined in [I-D.ietf-rats-architecture]. [Editor's Note: Definition might become obsolete, if replaced by Reference Values. Is there a difference between Claims and Values here? Analogously, why is not named Reference Claims in the RATS arch?] Comment > I suggest using Reference Values to keep consistent with the RATS arch. Reference Claims are used to appraise the Claims received from an Attester via appraisal by direct comparison. Comment > "Direct comparison" isn't the correct expression, the comparison can have other rules. Claim Selection ('claimSelection'): optional A statement that represents a (sub-)set of Claims that can be created by an Attester. Claim Selections can act as filters that can specify the exact set of Claims to be included in Evidence. An Attester MAY decide whether or not to provide all Claims as requested via a Claim Selection. Comment > The "all Claims" may be ambiguous, I'd like to double check, does it refer to all Claims that the Attester can create or refer to all Claims requested in the Claim Selection? Section 8.1 Challenge/Response Remote Attestation Comment > In the sequence diagram, some elements in the bracket are not defined in the "Information Elements" section, such as targetEnvironment, collectedClaims, eventLog. Should these elements be defined? Section 9 Additional Application-Specific Requirements Depending on the use cases covered, there can be additional requirements. An exemplary subset is illustrated in this section. Comment > Here starts to talk about "additional requirements", but I wonder there is no other places in this draft talking about requirement, so what are the basic requirements? Regards & Thanks!
