Making a WMS layer queryable

You need WFS for querying feature attributes.

	Hello All-
	
	I am attempting to serve a WMS layer that I would like to be
queryable (using the identify feature button/Query widget from
Chameleon).  The layer appears as it should when brought into a map, but
is not queryable, despite what it says in the layer information popup
window.  Other layers brought into the same map through other servers
are queryable.  I have searched the documentation and lists, but haven't
been able to find any answers.  Do I need to add something extra to the
mapfile (layer portion is pasted below)?  Both the context and
capabilities xml files show that the layer is queryable (=1) and I have
increased the tolerance ridiculously just to make sure a click hits on
the point.  Any suggestions would be greatly appreciated!  Thanks in
advance for your help.
