      "This module contains a collection of YANG definitions for
supporting the Broadband Forum requirements on reusable data
types as applicable to access network equipment. As such, this
module is specific to access network equipment (e.g.,
BBF-specified Access Nodes and FTTdp DPUs).

Specifically, this module defines common types used throughout
BBF data models.
