Documentation A concrete operation on coordinates that does not include any change of Datum. The best-known example of a coordinate conversion is a map projection. The parameters describing coordinate conversions are defined rather than empirically derived. Note that some conversions have no parameters. This concrete complexType can be used with all operation methods, without using an Application Schema that defines operation-method-specialized element names and contents, especially for methods with only one Conversion instance.
