25 25  The rules pertaining to how reported values map, are maintained in either a RepresentationMap, EpochMap, or DatePatternMap. A ComponentMap can only reference one of these mapping types to define how the reported values relate from source Dataset to the target Dataset. If a ComponentMap has more than 1 source or target, a RepresentationMap must be used to describe how the values map, as it is the only map which can define multiple source and target values in combination.
