The MassValueType is a SpecifiedDecimalType with an optional massUnit attribute that identifies the unit being used by its UnitName. If no value for the attribute is given in an instance file when a mass value is given, the unit type is the MassUnit specified in the PrimaryUnits element of a FileUnits element, if that specification exists, and kilograms if not.
