[Huizer, G.J.]

Thanks Bart for your quick reply. I guess we'll try WFS!

Regards,

Geert

Not possible using WMS GetFeatureInfo, the SLD parameter will be
ignored, it's not part of the GetFeatureInfo request at all.

Alternatively, you can create a WFS GetFeature request with the same
filter as in the SLD.

Best regards,
Bart
