          A dictionary of manufacturer-specific extended data fields, which
          may contain fields such as manufacturing plant, lot number, etc.

          These fields must not be used for programatic interrogation of
          an inventory object but may be useful for various human-oriented
          tasks, such as part failure analysis.  Any field needed for
          programmatic interrogation should be promoted to a first-class
          property in another Item or Decorator interface.
