Hi Jukka,

the current settings returns expected result with &srsName=EPSG:4326
as well. The original settings doesn't work neither with
&srsName=EPSG:4326 nor &srsName=EPSG::102067.

Yes, it looks like there would be a problem in case of several WFS
layers with different projections of the source data.

Cheers,

Mike
