       Assertion Framework for OAuth 2.0 Client Authentication and                           Authorization Grants


   This specification provides a framework for the use of assertions    with OAuth 2.0 in the form of a new client authentication mechanism    and a new authorization grant type.  Mechanisms are specified for    transporting assertions during interactions with a token endpoint;    general processing rules are also specified.

   The intent of this specification is to provide a common framework for    OAuth 2.0 to interwork with other identity systems using assertions    and to provide alternative client authentication mechanisms.

   Note that this specification only defines abstract message flows and    processing rules.  In order to be implementable, companion    specifications are necessary to provide the corresponding concrete    instantiations.
