class expressions for everything else

[Fawcett, David]

Tom, 

I am pretty sure that you can just put a class with no expression as the
last class in your layer.  

Have you tried:  

CLASS
 NAME "catchall"
 COLOR 255  255 255 
 OUTLINECOLOR 0 0 0
END

David.

Hi,

We have a LAYER with a number of CLASS definitions, each with a
EXPRESSION directive defined like:

CLASS
 NAME "foo"
 EXPRESSION ([Band] = 1)
 COLOR 0 255 0
 OUTLINECOLOR 0 0 0
END

...so that the data is displayed as per the CLASS definitions.  The
problem is that any data which does _not_ satisfy any of the CLASS
definitions is _not_ displayed.

Is there / how do we define a CLASS as the "catch all" definition (i.e.
colour everything else, similar to an OGC SLD "ElseFilter").

Any advice and / or suggestions are valued.

..Tom
