   In order to provide greater scalability, network confidentiality, and
   service independence, Segment Routing (SR) utilizes a Binding Segment
   Identifier (BSID).  It is possible to associate a BSID to an RSVP-TE-
   signaled Traffic Engineering Label Switched Path or an SR Traffic
   Engineering path.  The BSID can be used by an upstream node for
   steering traffic into the appropriate TE path to enforce SR policies.
   This document specifies the binding value as an MPLS label or Segment
   Identifier.  It further specifies an approach for reporting binding
   label/SID by a Path Computation Client (PCC) to the Path Computation
   Element (PCE) to support PCE-based Traffic Engineering policies.
