    I believe this would expand the scope of this document in a way I'd rather leave to the profiles.
    The AS can verify possession of a key in various ways, some of which may be provided by the 
    security protocol used between the client and the AS, which in turn would be defined in the profiles.

    Would you be ok with the following addendum: "Profiles of [framework] using this specification MUST define the proof-of-possession method used by the AS, if they allow clients to request the use of asymmetric keys as proof-of-possession key."?

    I suggest to update to add a 4.00 (Bad Request) here.
