That's odd? I've just tried to replace elements in a GeoServer WFS response
with empty ones, as follows:
<wfs:FeatureCollection xmlns="http://www.opengis.net/wfs";
xmlns:wfs="http://www.opengis.net/wfs"; xmlns:gml="
http://www.opengis.net/gml";
xmlns:GeoSolutions="http://www.geo-solutions.it"; xmlns:xsi="
http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://www.opengis.net/wfs
http://demo1.geo-solutions.it:80/geoserver-enterprise/schemas/wfs/1.0.0/WFS-basic.xsd

Eclipse says the above document is valid (that GeoServer is available to
the internet so you
can try out validation yourself)
