Good point.  I’d had that thought as well at one point but failed to express it in the draft.  Will do.

Subject: Re: [OAUTH-WG] JSON Web Token Best Current Practices draft describing Explicit Typing

Could some more guidance be provided around how to use the explicit typing with nested JWTs?
I'd imagine that the "typ" header should be in the header of the JWT that is integrity protected by the issuer?

The JWT BCP draft has been updated to describe the use of explicit typing of JWTs as one of the ways to prevent confusion among different kinds of JWTs.  This is accomplished by including an explicit type for the JWT in the “typ” header parameter.  For instance, the Security Event Token (SET) specification<http://self-issued.info/?p=1709> now uses the “application/secevent+jwt” content type to explicitly type SETs.

The specification is available at:

  *   https://tools.ietf.org/html/draft-sheffer-oauth-jwt-bcp-01

An HTML-formatted version is also available at:

  *   http://self-issued.info/docs/draft-sheffer-oauth-jwt-bcp-01.html
