+        WMS version 1.3 introduced the axis order sequence, so that for e.g. EPSG:4326 the bbox coordinate
+        values need to be flipped (LatLon instead of LonLat). The first map uses the incorrect (WMS 1.1) axis
+        order against a WMS 1.3 service, resulting in corrupted maps. The second map shows how to correctly
+        request a map in EPSG:4326 against a WMS 1.3 service.
