I never include FORMAT in my mapbooks.  I am guessing that it was there
to try and force 8-bit PNGs (instead of true color PNGs which are the
default when AGG is used with MapServer) because Internet Explorer 6
couldn't handle transparency in true color PNGs. 

I also don't use type="mapserver" in my mapbooks anymore.  Ticket #187
covers some of this.  There are likely also documentation updates that
should happen.
