I am having problems styling a KML network link via an external SLD.
Running v2.12.0
The network link that is generated looks like this:
service=wms&request=GetMap&version=1.1.1&format=application/vnd.google-earth.kml+xml&layers=mylayer&styles=generic&height=2048&width=2048&transparent=false&srs=EPSG:4326&format_options=AUTOFIT:true;KMATTR:true;KMPLACEMARK:false;KMSCORE:40;MODE:refresh;SUPEROVERLAY:false&sld=http://localhost/sld
The SLD returned from that url:
<?xml version="1.0"?>
<StyledLayerDescriptor xmlns="[http://www.opengis.net/sld](http://www.opengis.net/sld)" xmlns:ogc="[http://www.opengis.net/ogc](http://www.opengis.net/ogc)" xmlns:xlink="[http://www.w3.org/1999/xlink](http://www.w3.org/1999/xlink)" xmlns:xsi="[http://www.w3.org/2001/XMLSchema-instance](http://www.w3.org/2001/XMLSchema-instance)" version="1.0.0" xsi:schemaLocation="[http://www.opengis.net/sld](http://www.opengis.net/sld) StyledLayerDescriptor.xsd">
<NamedLayer>
<Name>mylayer</Name>
<UserStyle>
<Title>Hello</Title>
<FeatureTypeStyle>
<Rule>
<PointSymbolizer>
<Graphic>
<ExternalGraphic>
<OnlineResource xlink:type="simple" xlink:href="[http://maps.google.com/mapfiles/kml/pal3/icon55.png](http://maps.google.com/mapfiles/kml/pal3/icon55.png)"/>
<Format>image/png</Format>
</ExternalGraphic>
</Graphic>
</PointSymbolizer>
</Rule>
</FeatureTypeStyle>
</UserStyle>
</NamedLayer>
</StyledLayerDescriptor>
I get this exception:

Full disclosure, I know that an external SLD works in a standard WMS request, but I have never tried this in a KML network link. Should this work? If so any ideas on what I might be doing wrong?
Thanks,
Billy
