remove hack introduced for the parser to recognize CRS's from a GML 3.1.1 document when GEOT-1659 is fixed

                // http://jira.codehaus.org/browse/GEOT-1659 is fixed
                final String crs = raw.toString();
                if (crs.toUpperCase().startsWith("URN")) {
                    String code = crs.substring(crs.lastIndexOf(":") + 1);
                    try {
                        return CRS.decode("EPSG:" + code);
