Description

Attestaiton-Based Client Authentication says regarding the Client Attestation JWT:

iss: REQUIRED. The iss (issuer) claim MUST contains a unique identifier for the entity that issued the JWT. In the absence of an application profile specifying otherwise, compliant applications MUST compare issuer values using the Simple String Comparison method defined in Section 6.2.1 of [RFC3986].

As HAIP decides to mandate x5c for wallet attestation and this is what would be referenced for trust management, the iss value becomes obsolete and HAIP could say that iss can be omitted.

Research direction

Start by reading the cited Client Attestation JWT requirements in Attestation-Based Client Authentication and the HAIP requirements for x5c-based trust management. Update the relevant HAIP specification text so it clearly states whether the iss claim may be omitted, then verify that the wording is consistent with the profile's trust model.
