[udig-devel] WFS using an EPSG code unknown to uDig 1.1

 I don't know the "right" EPSG code. Our projection is EPSG:3059, but 
with only difference in
"PARAMETER["false_northing", -6000000.0]"

ours is:  "PARAMETER["false_northing", 0.0]"

the point is , that theoretically the correct representation is without 
those -6000000 meters
(which means pretending, that equator is moved 6000000 meters away from 
real location)
