Another thing that we should be aware of, is that GML 3.2 fixes (at least in the documentation) the axis order of EPSG:4326, which is y,x and not x,y.


This means that we must be careful that WFS services actually honour the axis order.

For the Groundwater Interoperability Experiment, we suggested that services that generates 3.1.1 GML and older will use x,y axis order while GML above 3.1.1 will use y,x axis order.
