Hi Allessandro,

Do you speak about these PR:
* https://github.com/qgis/QGIS/pull/8536 [Server] Null field value in GML has to be empty string 2.18 * https://github.com/qgis/QGIS/pull/8537 [Server][WFS] Null field value in GML has to be empty string 3.4

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

Regards,
René-Luc

Have you taken a look to the compliance OGC tests for WFS 1.X? If there's tests about this particular point, we'll know for sure if it's something to fix.

Regards.

    Hi all,

    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).

    If it is a bug I can work on the fix, but maybe I'm missing something.

    See:
    
http://osgeo-org.1560.x6.nabble.com/Why-the-WFS-does-not-return-the-NULL-value-field-td3802398.html

    apparently this is also what geoserver does.

    Any opinion?
