  Summary:
    CWMP and USP Data Model Definition Schema (DM Schema). DM Instances define CWMP
    or USP data models.  Within the schema, elements are grouped by category (simple
    types, complex types etc), and are in alphabetical order within each category.

  Comments or questions about this Broadband Forum data model should be
  directed to <info@broadband-forum.org>.
