only Allow True Curve Updates By True Curve Clients
True if the service only allows curve geometries to be updated by client code that identifies itself as a true curve-enabled client, indicating that client editing workflows account for curve segments correctly, false otherwise. This property can only be true if ArcGISFeatureServiceInfo.allowTrueCurvesUpdates is true.
By default, this API is not a true curve-enabled client. Use ArcGISEnvironment.serviceCurveGeometryMode to change this behavior.
