   This document defines a new BGP SAFI with a new NLRI to advertise a
   candidate path of a Segment Routing (SR) Policy.  An SR Policy is a
   set of candidate paths, each consisting of one or more segment lists.
   The headend of an SR Policy may learn multiple candidate paths for an
   SR Policy.  Candidate paths may be learned via several different
   mechanisms, e.g., CLI, NetConf, PCEP, or BGP.  This document
   specifies how BGP may be used to distribute SR Policy candidate
   paths.  New sub-TLVs for the Tunnel Encapsulation Attribute are
   defined for signaling information about these candidate paths.
