    - range is underspecified, as not all elements can appear as the range of a slot.

      for example to combine two enums

    comments:
    - This is to be used where not all data is expected to conform to having a required
      field
    - If a slot is recommended, and it is not populated, applications must not treat
      this as an error. Applications may use this to inform the user of missing data
