      Do you speak about these PR:<br>

      I don't think it is a GML specific issue, but something about XSD

              <div>Hi all,</div>
              <div><br>
              </div>
              <div>while working on QGIS server I noticed that WFS
                GetFeature returns NULL values as empty tags while
                according to the majority of the sources I've found it
                should not include it in the XML response (GML2 at
                least, I'm not sure about GML3 yet).</div>
              <div><br>
              </div>
              <div>If it is a bug I can work on the fix, but maybe I'm
                missing something.</div>
              <div><br>

              <div>See: <a

              <div>apparently this is also what geoserver does.</div>
