The Variable StartTime and the Method ResetStatistics are defined by the IStatisticsType and shall be used as defined by the Interface.
The OptionalPlaceholder <Quantity> is used to add additional Quantities to this group. In this case the abstract DataType 0:Number must be changed to a non-abstract DataType. The TypeDefinition may be chosen from BaseAnalogType and its subtypes.
The InstanceDeclarations of the FluidQuantitiesType have additional Attributes defined in Table 48.
