/** supplies a filtered subset of the original data source based on filtering criteria.

    interface to allow drill-down of result data.  The method this interface provides
    is used internally when calling <method>XDataPilotTable2::getDrillDownData</method>

    service does not implement this interface, then the aforementioned two methods
    will have no effect.
