So, nobody answered this one... yet, what I reported is a solid bug
in the WFS CITE tests sample data sets. Either that, or what
Carl Reed and Arliss Whiteside told me does not match with what the WFS
expert group is thinking.
What is the position of the WFS expert group and cite test managers?
Is "urn:x-ogc:def:crs:EPSG:6.11.2:4326" to be considered a lon/lat
CRS? Or is it the sample data broken? And if so, which version of
the coordinates is the right one?
