Hatching a polygon

[Gary Watry]

I know how to hatch a polygon,
but what I want to do is
1. if I create a polygon fill using

in the symbol.sym file

# Cross Hatch
  SYMBOL
    NAME "hatch"
    TYPE HATCH
  END

and in the mapfile

     STYLE
         SYMBOL 'hatch'
         COLOR 255 0 0
         OUTLINECOLOR 0 0 0
       ANGLE 45
         SIZE 10
         WIDTH 3
      END

How do I make the hatch so I can see the layer underneath the polygon 
instead of the white color between the hatch lines??

2 Is it possible to make a polygon fill semi-transparent so you can see 
the layer underneath the polygon through the fill??
