   This document defines a new BGP SAFI with a new NLRI in order 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
   a number of different mechanisms, e.g., CLI, NetConf, PCEP, or BGP.
   This document specifies the way in which 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.
