Please review the registration request in section 11.3 ( key elements copied below for convenience) at <https://datatracker.ietf.org/doc/draft-ietf-stir-passport/> Robert Sparks - STIR WG co-chair ------------ 11.3. JSON Web Signature and Encryption Header Parameter Registry 11.3.1. Registry Contents Additions Requested Header Parameter Name: "ppt" o Header Parameter Description: PASSporT extension identifier o Header Parameter Usage Location(s): JWS o Change Controller: IESG o Specification Document(s): Section 8.1 of [RFCThis] -------------- 8.1. "ppt" (PASSporT) header parameter Any using protocol can extend the payload of PASSporT with additional JWT claims. JWT claims are managed by an existing IANA registry as defined in [RFC7519] Section 10.1. Implementations of PASSporT MUST support the baseline claims defined in Section 5.2, and MAY support extended claims. If it is necessary for an extension to PASSporT to require that a relying party support a particular extended claim or set of claims in the PASSporT object, it can do so by specifying a "ppt" element for the PASSporT JOSE header. All values of "ppt" need to be defined in a specification which associates the new value of the "ppt" element with the required claims and behaviors. Relying parties MUST fail to validate PASSporT objects containing an unsupported "ppt". Using protocols MUST explicitly define the how each claim is carried in the using protocol and the rules for how the header and payload objects are constructed beyond the lexicographical and serialization rules defined in this document. Using protocols that carry the compact form of PASSporT, defined in Section 7, instead of the full form MUST use only mandatory extensions signaled with "ppt" - if a using protocol were to add additional optional claims to a PASSporT object it carried in compact form, relying parties would have no way to reconstruct the token. Moreover, using protocols that support the compact form of PASSporT MUST have some field to signal "ppt" to relying parties, as the compact form of PASSporT omits the JOSE header.
