Summary: This draft is on the right track but has open issues, described in the review.
* This draft defines the new claim "origid" for the Personal Attestation Token used in the SHAKEN framework, but does not give any privacy considerations about it and its use. [RFC6973] suggests that the privacy considerations of IETF protocols be documented. As required by [RFC7258], work on IETF protocols needs to consider the effects of pervasive monitoring and mitigate them when possible. I don't know SHAKEN well enough to comment on privacy issues on that, but this draft, as part of the IETF work, should have privacy considerations, particularly considering the "origid" claim.
* Section 4: the term "verified association" is not defined in this document, nor in [RFC8225], nor in the SHAKEN spec referenced. Is there a way to clarify what is meant by it? It could be a reference.
* Terminology: I would have appreciated a short sentence mentioning [RFC8225] in the Terminology section.
* Section 9: [RFC8224] appears without link.
* Acknowledgements: "The authors would like
