Re: [Geoserver-users] WFS GetFeature with zero results, different in 1.6.5 and 1.7.0

[Justin D. <jde...@op...>]

Hi Björn,

So I believe the 1.7.0 behavior is a bug. Either it should include no 
boundedBy element or it should include the gml:null element as in 1.6.5. 
 From a schema point of view both would be valid.

 From a spec point of view I am not sure... I think that question would 
better be answered by the spec writers on the wfs-dev mailing list, 
wf...@op....
