[mapserver-dev] Disabling GML output for one layer

[Rahkonen Jukka (Tike)]

Hi,

I had not noticed that DUMP TRUE has no effect any more.

I made some tests with our WMS services. As documented, adding TEMPLATE to LAYER makes a vector layer queryable (weird for my mind) and adds the two default info formats, text/plain and GML. It is possible to add more info formats with wms_feature_info_mime_type but it does not seem possible to remove text/plain or GML formats. However, with wms_inlude_items and gml_include_items it is possible to control the attributes which are sent with the response. 

I had never before noticed that all RASTER layers are queryable by default and a LAYER lever "wms_enable_request" "* !GetFeatureInfo" must be used for disabling GetFeatureInfo.

When it comes to the actual question, the list of supported info formats is a service level element in WMS GetCapabilities. Therefore I believe that if GML output is supported for one layer, then it must be supported for all layers. Empty response with info_format=GML is probably the best that you can get.

I almost feel that it is a bug that raster layers must explicitly set to not-queryable when it is the opposite with vector layers.
