PoP for revocation

Hi all,

P.[277] of the spec. [1] says that:
Services SHOULD accept Proof of Possession of the private key component
of a public key to effect revocation of any key binding bound to that
key.

As the element ProofOfPossession is not allowed for a RevokeRequest, I
understand that possession of the key may be proved in the
KeyBindingAuthentication element. I think that maybe the reference to
"Proof of Possession" should be removed from there to make things
clear...

Cheers,
