     115The {{{<Error>}}} element in the schema is used to capture any string tokens in the {{{COORDINATES}}} operation parameter that does not parse out to a space-separated coordinate pair. Thus a successful batch transformation operation is one whose list of {{{<TransformedCoordinate>}}} elements do not have any {{{<Error>}}} elements set.
     116
     117This mapagent operation supports both {{{GET}}} and {{{POST}}} methods. Bigger coordinate lists can be specified via {{{POST}}} to overcome natural (client-and-server-imposed) limits in query string size.

     134 * Verify {{{SELECTFEATURES}}} and {{{SELECTAGGREGATES}}} behave as before without the {{{TRANSFORMTO}}} parameter
     135   * Verify {{{SELECTFEATURES}}} and {{{SELECTAGGREGATES}}} (with {{{SpatialExtent}}} aggregate) output transformed coordinates according to the {{{TRANSFORMTO}}} parameter
     136   * Verify that {{{SELECTFEATURES}}} and {{{SELECTAGGREGATES}}} (with {{{SpatialExtent}}} aggregate) with {{{CLEAN=1}}} {{{TRANSFORMTO=<output_cs>}}} outputs GeoJSON with transformed coordinates in {{{output_cs}}}
     137 * Verify {{{CS.TRANSFORMCOORDINATES}}} with malformed {{{COORDINATE}}} strings, properly puts un-parseable tokens into the {{{<Error>}}} element of their respective {{{<TransformedCoordinate>}}} element in the operation response.
