                 * the CoordinateOperation WKT, we omit non-EPSG parameters when we have determined that we are
                 * about to describe an EPSG operation. We could generalize this filtering to any authority, but
                 * we don't because few authorities are as complete as EPSG, so other authorities are more likely
                 * to mix EPSG or someone else components with their own. Note also that we don't apply filtering
                 * on MathTransform WKT neither for more reliable debugging.
