Hi,
A bit more testing: WFS 1.1.0 does not accept "Intersect" filter but gives an
error. However, WFS 1.0.0 is accepting all filters, it is just doing nothing
with not recognised ones. This one gives me also all the states.
<wfs:Query typeName="topp:states">
<Filter>
<foo>
<PropertyName>the_geom</PropertyName>
<gml:Point srsName="http://www.opengis.net/gml/srs/epsg.xml#4326";>
<gml:coordinates>-74.817265,40.5296504</gml:coordinates>
</gml:Point>
</foo>
</Filter>
</wfs:Query>
