1.  Introduction

   This document defines data models for DS-Lite [RFC6333], using the
   YANG data modeling language [RFC6020].  Both the Address Family
   Transition Router (AFTR) and Basic Bridging BroadBand (B4) elements
   are covered by this specification.  As a reminder, Figure 1
   illustrates an overview of the DS-Lite architecture that involves
   AFTR and B4 elements.
