    2424In the current design of the OSGeo OGC FDO WMS Provider(s), no mechanism exists to allow a client to retrieve all supported CS’s for a specific WMS feature class, neither for image format and style information.
    25 In order to resolve this issue, the WMS providers should be enhanced to add 3 new commands for retrieving all supported image format, style and CS information from WMS server.
