    "This module defines the shared profiles and related lists
     to be referenced when configuring MEF Services. Service
     Providers are expected to define a set of profiles for
     Service Attributes associated with Bandwidth, L2CP, CoS,
     and so on. These are expected to be slowly changing as
     they reflect the Products offered by the Service Providers
     to their Subscribers.
