+ * MapServer 6 (the version available on Debian Wheezy) outputs incorrect
+ * GML for MultiCurve geometries - see https://github.com/mapserver/mapserver/issues/4924
+ * The end result is that features with 'curveMembers' elements in their
+ * geometries will be missing from the map as the default GML parser doesn't
+ * know how to handle these elements.
+ * This subclass works around the problem by parsing 'curveMembers' elements.
