Transparency based on classification, possible?

[Fawcett, David]

No.  

Transparency is set at the layer level.  Take a look at:
http://mapserver.gis.umn.edu/docs/reference/mapfile/layer

If you want to use URL variable substitution, you could probably change
the transparency of the LAYER on the fly, but not at the class level.

Hello,

Is it possible to set the transparency of layer symbolization based on
the classification? Something similar to the effect of:

LAYER
	...
	CLASS
		EXPRESSION "expr0"
		TRANSPARENCY 50
	END CLASS
	CLASS
		EXPRESSION "expr1"
		TRANSPARENCY 70
	END CLASS
END LAYER

Thanks.
