Hi,

at the moment it is not implemented i think. But it's open source, so
you can extend the source/wms.py and config/loader.py a little bit.
Maybe like this - but not really tested:

change in config/loader.py in method fi_source

fi_source = WMSInfoSource(fi_client, fi_transformer=fi_transformer)

to

coverage = self.coverage()
fi_source = WMSInfoSource(fi_client, fi_transformer=fi_transformer,
coverage=coverage)

and class WMSInfoSource(InfoSource): in source/wms.py

to

class WMSInfoSource(InfoSource):
     def __init__(self, client, fi_transformer=None, coverage=None):
         self.client = client
         self.fi_transformer = fi_transformer
         self.coverage = coverage

     def get_info(self, query):
         if self.coverage and not self.coverage.contains(query.coord,
query.srs):
             return None
         doc = self.client.get_info(query)
         if self.fi_transformer:
             doc = self.fi_transformer(doc)
         return doc

regards Holger
