      "Configuration and operational state parameters relating to the
segment routing. This module defines a number of elements which are
instantiated in multiple places throughout the OpenConfig collection
of models.

Particularly:
 - SRGB+LB dataplane instances - directly instantied by SR.
 - SRGB+LB dataplane reservations - instantiated within MPLS and future SR
				 dataplanes.
 - SR SID advertisements - instantiated within the relevant IGP.
 - SR-specific counters - instantied within the relevant dataplane.";
