 CoMID triples typically encode assertions made by the CoRIM author about Attesting or Target Environments and their security features, for example measurements, cryptographic key material, etc.
 
 This specification defines two classes of triples, the Mandatory to Implement (MTI) and the Optional to Implement (OTI).
-The first set of triples is essential to the fundamental principles of Evidence appraisal as illustrated in {{-rats-arch}} and {{-rats-endorsements}} and is mandatory to implement (MTI).
+The MTI triples are essential to basic appraisal processing as illustrated in {{-rats-arch}} and {{-rats-endorsements}}.
 Every Verifier MUST support the MTI triples, if CoRIM processing is supported by the Verifier.
 The second set of triples is included in this specification as they are generally useful across profiles and are optional to implement (OTI).
 Ever Verifier SHOULD support OTI triples, if CoRIM processing is supported by the Verifier, unless there are good reasons not to do so, such as restrictions imposed by constrained resource environments, reduced code complexity in support of periodic code review, or scoping to Attester simplicity.
