2023-06-14: TR-106 Amendment 12

TR-106 Document

• Updated the Mountable Object and Mount Point descriptions to
  indicate that all top-level objects (other than mount points) are
  mountable
• Updated path scoping rules to indicate that a path that starts
  with a period (.) is relative to its mount point (if mounted)
  or to the Root or Service Object (otherwise)
• Updated the hidden and secured attributes to clarify that they
  can't both be set to true, and that for CWMP secured means
  the same as hidden
• Tightened the version attribute definition. It can only be
  used when the version is later than the parent version,
  except that it always has to be specified for Objects and
  Profiles. Also added a new section on the use of the version
  attribute
• Clarified that defaults defined in components will be "promoted"
  to parameter defaults when used in command or event arguments
• Fixed the rules governing modifications of existing models. The
  basic rule is that the value space can only be expanded, never
  contracted
• Added a new section on the DMR (Data Model Report) Schema

DM Data Model Definition Schema (DM Schema)

• Supported XSD v1.1, which allows more rigorous validation, e.g.,
  use of appropriate attributes when creating and modifying items
• Added defaults for various attributes, e.g. access, minEntries
  and maxEntries default to readOnly, 1 and 1 respectively
• Deprecated the mountType attribute's none and mountable
  values, because mountable objects are now determined automatically
• Made the uniqueKey/functional and the command/async
  attributes mandatory
• Relaxed rules governing the order of top-level elements such as
  import, dataType and component; they can now occur in any
  order
• Tightened up the use of dmr: attributes, which can now only be
  used on elements where they make sense
• Fixed a few bugs, e.g., added a template element uniqueness check

Data Model Report Schema (DMR Schema)

• Added noUnitsTemplate to suppress "missing {{units}}
  template" warnings
• Added previousCommand and previousEvent attributes

Device Type Schema (DT Schema)

• Updated to reference latest published DM Schema version (v1.10)
• Note that the DT Schema is v1.10 to match the DM Schema (DT
  Schema v1.7, v1.8 and v1.9 were skipped)
