[mapserver-users] SLD with LayerFeatureConstraints

[Meine Toonen]

Thanks for the info. 
Will the LayerFeatureConstraints options be available in the future, or is filtering only supported in an UserStyle? Couldn't find it in the trac.

Met vriendelijke groet,

  Sld:LayerFeatureConstraints is not supported by MapServer, or SLD 1.0.0.
  FYI here's an example of applying filters to SLD:
