I wonder one thing. If you run this http://193.175.162.189/geoserver/wcs?request=DescribeCoverage&identifiers=raster_example_20130208_113005_078&VERSION=1.1.0
You will see wcs:SpatialDomain> <ows:BoundingBox crs="urn:ogc:def:crs:EPSG::4326" dimensions="2"> <ows:LowerCorner>-55.833333335 -117.00033333499998</ows:LowerCorner> <ows:UpperCorner>32.666668435 -34.66699835499999</ows:UpperCorner> </ows:BoundingBox> <wcs:GridCRS><wcs:GridBaseCRS>urn:ogc:def:crs:EPSG::4326</wcs:GridBaseCRS> <wcs:GridType>urn:ogc:def:method:WCS:1.1:2dGridIn2dCrs</wcs:GridType> <wcs:GridOrigin>-116.91699999999997 32.5833351</wcs:GridOrigin> <wcs:GridOffsets>0.16666667 0.0 0.0 -0.16666667</wcs:GridOffsets> <wcs:GridCS>urn:ogc:def:cs:OGC:0.0:Grid2dSquareCS </wcs:GridCS></wcs:GridCRS> </wcs:SpatialDomain> So Geoserver is sending coordinates in lat-lon order for the GridOrigin. I can see that GDAL is automatically adding quite a lot metadata to the WCS.XML configuration file and this same GridOrigin gets saved also to there.

If Geoserver folks will tell that the GDAL WCS 1.1.0 request is wrong then you can try to get an answer to question b) by sending a question with this information into GDAL developer mailing list. Yes, WCS 1.1 has swapped axis just like WFS 1.1. See this table, it applies to WCS 1.1 as well: http://docs.geoserver.org/latest/en/user/services/wfs/basics.html#axis-ordering Given that as usual servers tend to implement axis swapping inconsistently (or not at all) a probably wise move on the GDAL side would be to allow the user to manually control which CRS to handle as swapped, and which not.
