overlapping polygons at the CLASS level, I solved it by using a hatch symbol
that had a minimum spacing value, thus allowing linework to appear through the
hatching. It will have a slight affect on the colour of the polygon on top but
works well.</span></font></p>

your classes into separate layers. This would allow you to use
transparency, but would of course multiply the number of layers and may give
you a very small performance hit (which may likely be negligible). </span></font></p>

solid. Underlying polygon doesn't have to have any, while the top polygon
can have any transparency level you want - probably somewhere between 40 and
60% if you want both to be approximately equally visible.</span></font></p>

color:blue'>Or you can simply set an OUTLINECOLOR and no COLOR, which means you
will get an outline and no fill, which will show any underlying polygons as
long as they don't directly overlap the same lines. Any overlapping lines
can be identified by making the outline line thicker and a different color, so
whoever is viewing the map can see that there are multiple polygons there.</span></font></p>
