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

onderhoudsinstantiecode FROM wwall w, kpxy k WHERE NOT (k.soort LIKE 
'D') and (w.x &gt; %xmin%) and (w.x &lt; %xmax%) and (w.y &gt; %ymin%)

            <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?
