<title>OpenID Connect Relying Party Metadata Choices 1.0 - draft 00</title>

OpenID Connect 1.0 is a simple identity layer on top of the OAuth 2.0
protocol. It enables Clients to verify the identity of the End-User based
on the authentication performed by an Authorization Server, as well as to
obtain basic profile information about the End-User in an interoperable and
REST-like manner.
This specification extends the OpenID Connect Dynamic Client Registration 1.0
specification to enable RPs to express a set of supported values
for some RP metadata parameters, rather than just single values.
This functionality is particularly useful when Automatic Registration,
as defined in OpenID Federation 1.0,
is used, since there is no registration response from the OP
to tell the RP what choices were made by the OP.

Once the style has stabilized and has been adopted as an official RFC style,
this can be consolidated so that style settings occur only in one place, but
