	I completely agree. The issue of CSS vs. XSL FO is now a well known issue
and has been almost completely hased out. XSL FO is akin to DSSSL FO which
is itself a well known standard. If we are *only* concerned with HTML and
web browser display, the argument for a need for XSL FO is perhaps
reasonable (though there are arguments agains this as well). There does
appear to be a need for formatting languages which are distinct from
HTML+CSS e.g. PDF/postscript/RTF/TeX etc etc etc.

	As it stands today, it is <em type="huge">far</em> easier to take a FOT and
transform this as PDF,postscript,HTML+CSS or RTF than it is to transform
from a HTML+CSS tree. The real argument (IMHO) is whether XSL FO is even up
to this task, not in comparison with CSS but in comparison with DSSSL.
