Usage of encrypted_response_enc_values_supported with proposal for JOSE HPKE #682
Description
With the latest proposal for JOSE HPKE as outlined in ietf-wg-jose/draft-ietf-jose-hpke-encrypt#84, the enc header in the JWE will not be used with the integrated encryption mode. This means that in the event only this mode of HPKE is supported the text around the definition of this meta-data parameter is potentially problematic due to its irrelevance. See below for the current text.
OPTIONAL. Non-empty array of strings, where each string is a JWE [RFC7516] enc algorithm that can be used as the content encryption algorithm for encrypting the Response. When a response_mode requiring encryption of the Response (such as dc_api.jwt or direct_post.jwt) is specified, this MUST be present for anything other than the default single value of A128GCM. Otherwise, this SHOULD be absent.
