1.  Introduction

   This document defines a YANG [RFC7950] data model for for
   representing, managing, and controlling IETF network slices, defined
   in [I-D.nsdt-teas-ietf-network-slice-definition]

   The defined data model is an interface between clients and providers
   for configurations and state retrievals, so as to support network
   slicing as a service.  Through this model, a client can learn the
   slicing capabilities and the available resources of the provider.  A
   client can request or negotiate with a network slicing provider to
