Re: [mapserver-users] Styling KML output
So you're using the OGR driver. I wouldn't expect that to leverage MapServer class/styles at all - more of a data dump. There is a separate KML driver (see https://mapserver.org/output/kml_output.html) and you can also use templates to generate KML and define styles as part of the templates

I've setup KML/KMZ output for WFS with these definitions: OUTPUTFORMAT NAME kml DRIVER "OGR/KML" MIMETYPE "application/vnd.google-earth.kml+xml" IMAGEMODE FEATURE EXTENSION "kml" FORMATOPTION "FORM=simple"
