1.2.  Terminology

   Bearer Token
      A security token with the property that any party in possession of
      the token (a "bearer") can use the token in any way that any other
      party in possession of it can.  Using a bearer token does not
      require a bearer to prove possession of cryptographic key material
      (proof-of-possession).

   All other terms are as defined in "The OAuth 2.0 Authorization
   Framework" [RFC6749].
