Technical Summary

   PASSporT is specified in RFC 8225 to convey cryptographically-signed
   information about the people involved in personal communications.
   This document extends PASSporT to include an indication that a call
   has been diverted from its original destination to a new one.  This
   information can greatly improve the decisions made by verification
   services in call forwarding scenarios.  Also specified here is an
   encapsulation mechanism for nesting a PASSporT within another
   PASSporT that assists relying parties in some diversion scenarios.

Working Group Summary

  The STIR WG reached consensus, and there is strong support for
