help w/ WFS request

[Bart van den Eijnden (OSGIS)]

Hi John,

1) what Mapserver version are you using?
2) if you do a DescribeLayer request, what is the name of the geometry 
property (is it really the_geom like in your request)?

Mapserver's response indicates an empty feature collection, so the 
boundedBy is gml:null.

Best regards,
Bart
