[gdal-dev] Issues with WFS driver

Hi Ari,

I fail to see how below is related to streaming mode... This is a generic 
behaviour of the GML driver

The issue is that, as far as I've understood, you use a schema not generated 
by the GML driver with GML output generated by the GML driver.

OGR layers have a concept of GetGeometryColumn(), in read mode. The GML driver 
is able to read a GML whose geometry name is not "geometryProperty". What 
could be done is to add a layer creation option to specify a geometry name 
instead of the default "geometryProperty". Would you be interested in that ?
