058     *   This interface is kept conformant with the specification published in 2003.
059     *   The 2007 revision of ISO 19111 removed the <code>GeographicCRS</code> and
060     *   <code>GeocentricCRS</code> types, handling both using the <code>GeodeticCRS</code> parent type.
061     *   GeoAPI keeps them since the distinction between those two types is in wide use.
