It would be propably appropriate for the WCS driver to do so as well, as nothing else in GDAL can deal with rasters referenced in lat,long order.</p>

So, treat lat,lon and north,east always as exceptions. And in this
case add an option to make that exception when appropriate and when
writing the BoundingBox into the request. (But not when reading
GridOrigin. However, I still have to see what other servers say.)<br>

We'll see what MapServer developers say. I submitted an issue to its
github.<br>
