If this is not specified in the DataStructureDefinition then the representation specified for Concept (coreRepresentation) is used. Measure, and DataAttribute may be also represented by multilingual text (as seen in the DataSet diagram further down). An exception is the MetadataAttribute, where its Representation is specified in the MetadataStructureDefinition.
