   In order to provide greater scalability, network opacity, and service
   independence, Segment Routing (SR) utilizes a Binding Segment
   Identifier (BSID).  It is possible to associate a BSID to RSVP-TE
   signaled Traffic Engineering Label Switching Path or binding Segment-
   ID (SID) to SR Traffic Engineering path.  Such a binding label/SID
   can be used by an upstream node for steering traffic into the
   appropriate TE path to enforce SR policies.  This document proposes
   an approach for reporting binding label/SID to Path Computation
   Element (PCE) for supporting PCE-based Traffic Engineering policies.
