Remarks
Use LayerResultOptions when you want to customize the results of a MapServer query - for example, when you want field names (instead of field aliases) or data in native format or in some cases you may want to limit or adjust the geometry being returned.
Since LayerResultsOptions is part of of the LayerDescription any settings made for LayerResultsOptions will only affect those methods that include the LayerDescription (or MapDescription whcih contains LayerDescriptions) as a parameter. These include Find, Identify, QueryData, QueryRowIDs, QueryRowCount, QueryFeatureCount2, QueryFeatureIDs2, QueryFeatureData2 and QueryHyperlinks. QueryHyperLinks always returns geometry regardless InlcudeGeometrys value, but honors GeometryResultOptions.
