By default, the DataMember will be set to "DimensionStatesResult" and this result will be used to create the tag cloud based on the dimension whose ID is specified in the DimensionID property. Another possible value for DataMember is to set it to a single dimension, for example, 'DimensionStatesResult.RefinableDimensionStates["Region"]'.
