    <p>I don't think that's a mistake. The choice of abbreviations is
      indeed somewhat random, or might depend on local usages. Using the
      direction will be more robust.<br>

          (Switzerland) I found something strange: <br>
        </div>
        <div>    CS[Cartesian,2],<br>
                  AXIS["easting (Y)",east,<br>
                      ORDER[1],<br>
                      LENGTHUNIT["metre",1]],<br>
                  AXIS["northing (X)",north,<br>
                      ORDER[2],<br>
                      LENGTHUNIT["metre",1]],</div>
        <div><br>
        </div>
        <div>The first axis is east... however the abbreviation is "Y".
          Is there any reason for that? Is it just a mistake in EPSG
          data? I have the impression that I should ignore that
          abbreviation, and relay only on the direction. But it is
          getting hard ;)</div>
        <div><br>

        <div>Thanks.<br>
