  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.

  Issue History (Filename: Approval Date: Publication Date: Changes):
    * cwmp-datamodel-1-0.xsd: November 2008: corresponds to TR-106 Amendment 2
    * cwmp-datamodel-1-1.xsd: September 2009: corresponds to TR-106 Amendment 3
      - made import/@file a URI and optional (in line with DT Schema)
      - added RangeFacet step attribute
    * cwmp-datamodel-1-2.xsd: March 2010: corresponds to TR-106 Amendment 4
      - added uniqueKey/@functional attribute
      - supported #.A relative path syntax (parent)
    * cwmp-datamodel-1-3.xsd: November 2010: corresponds to TR-106 Amendment 5
      - removed the referential check done on object/@enableParameter
      - removed the referential check done on object/uniqueKey/parameter/@ref
      - updated all of the unique parameter-name constraints so that the
        parameter/@base attribute is also considered.
      - updated all of the unique object-name constraints so that the
        object/@base attribute is also considered.
      - added "prefix" option to the description/@action attribute
      - made import/@file attribute required for import element 
      - removed size facet's default maxLength on string/base64/hexBinary 
        parameters
      - added syntax/@command attribute to the syntax element
    * cwmp-datamodel-1-4.xsd: July 2011: corresponds to TR-106 Amendment 6
      - added top-level @file attribute
    * cwmp-datamodel-1-5.xsd: September 2013: October 7 2013: corresponds to TR-106 Amendment 7
      - added profile/@minVersion attribute
      - allowed uniqueKey parameters to be in sub-objects
      - defined BibliographyReference type (previously anonymous)
      - clarified encoding and character set requirements
      - clarified that unique key parameters can't be lists
      - added UUID data type
      - added ListNesting data type, nestedBrackets attribute, and allowed
        use of the list facet in named data type definitions
    * cwmp-datamodel-1-6.xsd: March 2018: March 26 2018: corresponds to TR-106 Amendment 8
      - supported USP commands, events and mount points
    * cwmp-datamodel-1-7.xsd: September 13 2019: September 13 2019:
      - supported implementation defaults, version attribute, description templates,
        writeOnceReadOnly access type and the decimal datatype
