    A service that acts as a DataPilot data source can optionally implement this
    interface to allow drill-down of result data.  The method this interface provides
    is used internally when calling XDataPilotTable2::getDrillDownData()
    or XDataPilotTable2::insertDrillDownSheet().  If the data source
    service does not implement this interface, then the aforementioned two methods
    will have no effect.
