      \brief  A class that contains complemental DataSetType information about a DataSet 
              that holds observations.
 
      This class contains complemental DataSetType information about a 
      DataSet that holds observations. 
 
      An observation is a result of a measurement associated to a discrete 
      time instant or period which assigns values to a phenomenon. It follows
      the OGC's Observation and Measurement (O&M) specification.
      An observation is composed of: (1) a phenomenon time, (2) a valid time, 
      (3) a result time and (4) observed values. 
      
      Thus, this class has the indexes of the DataSet properties that contains the
      phenomenon time, the valid time, the result time and the observed values.
