[UMN_MAPSERVER-USERS] What happend to OGR OVF layers since gdal 1.3.1

[Huub Fleuren]

Hi List,

This is question about different gdal versions working on OVF layers

OGRINFO of any GDAL version gives me the data from such a layer using 
ogrinfo layer.ovf -al
Versions 4.5, 4.8, 4.10.0 4.10.2  of mapserver  compiled against gdal 
1.3.1 work OKE but later GDAL versions give errors

'D') and (w.x &gt; %xmin%) and (w.x &lt; %xmax%) and (w.y &gt; %ymin%) 
and (w.y &lt; %ymax%) and (w.kruispuntnummer = k.kp_nr)</SrcSQL>

           <GeometryField encoding='PointFromColumns' x='x' y='y'/>
       </OGRVRTLayer>
   </OGRVRTDataSource>"
   DATA "kpxy" # the name of the OGRVrtLayer

etc.

I did not find documentation on changes concerning OVF layers. What 
happened?
