1.  Introduction

   JSON Web Token (JWT) [RFC7519] is a mechanism that is used to
   transfer claims between two parties across security domains.  Nested
   JWT is a JWT in which the payload is another JWT.  The current
   specification does not define a means by which the enclosing JWT
   could have its own Claims Set, only the enclosed JWT would have
   claims.

   This specification extends the scope of the Nested JWT to allow the
   enclosing JWT to contain its own Claims Set in addition to the
   enclosed JWT.
