The VariableStartTime and the MethodResetStatistics are defined by the IStatisticsType and shall be used as defined by the Interface.

The OptionalPlaceholder<Quantity>is used to add additional Quantitiesto this group. In this case the abstract DataType0:Numbermust be changed to a non-abstract DataType. The TypeDefinition may be chosen from BaseAnalogType and its subtypes.

The InstanceDeclarationsof the FluidQuantitiesTypehave additional Attributesdefined in Table 48.
