I send this filter in a WFS GET request:
&filter=<Filter
xmlns="http://www.opengis.net/ogc";><Intersects><PropertyName>the_geom</PropertyName><Polygon
xmlns:gml="http://www.opengis.net/gml"; srsName="EPSG:4326"

srsDimension="2">9.65370556674251 55.5315919660268 11.0768630778924

55.5315919660268</posList></LinearRing></exterior></Polygon></Intersects></Filter>
In PostgreSQL these WHERE clauses are used for respectively VERSION=1.0.0 and
1.1.0:
1.0.0:
(st_intersects(the_geom,ST_GeomFromText('POLYGON ((9.6537055667425093
55.5315919660268023, 11.0768630778923995 55.5315919660268023,
11.0768630778923995 55.2775349059760970, 9.6537055667425093
55.2775349059760970, 9.6537055667425093 55.5315919660268023))',4326)) = TRUE)
1.1.0:
(st_intersects(the_geom,ST_GeomFromText('POLYGON ((55.5315919660268023
9.6537055667425093, 55.5315919660268023 11.0768630778923995,
55.2775349059760970 11.0768630778923995, 55.2775349059760970
9.6537055667425093, 55.5315919660268023 9.6537055667425093))',4326)) = TRUE)
The the 1.1.0 request the axis order is being flipped in the WHERE clause (is
lat/lon). But shouldn't WFS 1.1.0 respect the axis order defined by the EPSG
definition?
To me it seems that MapServer is always flipping axis order when using version
> 1.0.0 regardless of EPSG definition. Can this be right?
Axis orders (taken from GeoServer web-site):
EPSG:4326
longitude/latitude assumption
http://www.opengis.net/gml/srs/epsg.xml#xxxx longitude/latitude strict
urn:x-ogc:def:crs:EPSG:xxxx
latitude/longitude strict
urn:ogc:def:crs:EPSG::4326
latitude/longitude strict
