          "This module contains a collection of YANG definitions for
         supporting the Broadband Forum requirements on management of
         ITU-T Passive Optical Network (PON) interfaces as defined in
         ITU-T G.984.x, G.987.x, ITU-T G.989.x and ITU-T G.9807.x. As
         such, this module is specific to access network equipment (e.g.,
         BBF-specified Access Nodes and FTTdp DPUs).
    
         Specifically, this module defines Optical Network Unit (ONU)
         power management at the virtual Access Network Interface (vANI).
