          A {{property(representation,DataItem)}} specifies the format and

          {{property(representation,DataItem)}} is `VALUE` indicating the format
          as specified in {{citetitle(MTCPart3)}}. A
          {{property(representation,DataItem)}}, other than `VALUE`, will modify
          the element name of the {{term(observation)}} by appending the pascal
          case of the {{property(representation,DataItem)}} as follows:

          `TEMPERATURE` and {{property(representation,DataItem)}} of
          `TIME_SERIES` becomes `TemperatureTimeSeries` \item **DEPRECATED** A

          \item A {{block(DataItem)}} with {{property(representation,DataItem)}}
          `TIME_SERIES` **MUST** have a {{property(category,DataItem)}} `SAMPLE`

          {{property(category,DataItem)}} `EVENT` \item A {{block(DataItem)}}
          with {{property(representation,DataItem)}} `DATA_SET` **MUST** have a
