We have not even investigated how to use xpaths for complex properties in an SLD. This is precisely what I want to look into. If it's not too hard I'll make the changes myself, That would be excellent! otherwise I'll roll our a simple feature equivalent of the complex featuers that can be used for web mapping That is what out app-schema users do at the moment. Not pretty, but it works. The main problem is that GetFeatureInfo gives simple data. Better would be if GetFeatureInfo gave a complex (app-schema) WFS response. Hmm... I don't think that is possible at all with WMS 1.1: even using the GML output the spec says the output should be GML2. Maybe WMS 1.3 says GML3, I don't know, but the thing is, as long as thethe WMS spec says something about the gml version to be used you cannot go out with an app-schema that uses a different gml version Cheers Andrea ----------------------------------------------------- Ing.

If I am reading this correctly, the standard is GML2 for WMS1.3 . This also affects my plans to activate more formats for app-schema layers in the Layer Preview webpage. It sounds like there is an existing tool somewhere to convert a complex feature to GML2, with loss of information.
