I'd rather that we stayed with working group drafts in the examples. So I
would counter-propose the following text:
"The public key(s) referenced by "jwks_uri" (or contained in the "jwks") can be
used in a variety of use cases. For example, the signature of a JWT
[I-D.ietf-json-web-token] signed by the client can be verified by the
authorization server using these keys. Another example is that the
authorization server can use the indicated public keys to verify a request to
the token endpoint that utilizes the JWT assertion profile as described in
Section 4.2 of [I-D.ietf-oauth-assertions]."

What about the following text:
jwks_uri
.... <previous text in Section 2 of
http://tools.ietf.org/html/draft-ietf-oauth-dyn-reg-18> .....
"The public key(s) referenced by jwks_uri (or contained in the jwks) can be
used in a variety of use cases. For example, the AS can use the indicated
public key to verify a request to the token endpoint that utilizes the JWT
assertion profile as described in Section 4.2 of [I-D.ietf-oauth-assertions].
Another use case is for the AS to use the public key of a client to encrypt a
symmetric proof-of-possession key sent to the client, as described in Section
4.2 of [I-D.bradley-oauth-pop-key-distribution]."
Ciao
