Description
Currently Geoserver renders polylines as polygons if a fill is specified in the .sld For MapInfo and Oracle based maps this can be problematic since multiple geometry types can be stored in the same table and they should only be filled if they are in fact a polygon. Polylines should not be filled at all. Can an extension be provided to WMS to override the default behaviour?

This is the SLD mandated behavior, but can be worked around using filter functions as described here:
