Steve,

I'm slightly at a loss here. What is the query information exactly? I  
cannot remove the CLASSITEM from the other layers since they are raw  
grids which need to be classified. If I remove TEMPLATE and the gml_*  
items from a  layer mapserver complains that layers are not queryable.

Thanks for the help,
