Mike, it's quite possible that set("template", "") is not sufficient to disable 
querying.  This would have to be investigated, so I am filing this as a bug so 
that we don't forget.

The template parameter is checked for NULL not for an empty string (should do
both obviously). With swig it's not too bad since the is a way to set pointers
to NULL via the scripting language. So I updated msIsLayerQueryable to check for
NULL and zero length template strings. Should fix this problem but I'll let you
guys close it out...

In the 4.1 (CVS) version it is now possible to set("template", null), that fixes
the issue for the PHP MapScript interface.
