Not _any_ format, but formats, yes. If XSLFO are not (like dssl
before them) intended to be cross format style description, what's the
point? 

In xmltex for example you can either pass your TEI file straight to TeX
or you can first munge it into FO and then pass that to TeX.
Currently the trip through FO makes it harder rather than easier to
achieve many things that one might want to achieve. Far less control
over floats, running heads etc, no (standardised) control over pdf 
features such as bookmarks andacrobat's initial state.

However the benefits of FO are (hopefully) that one may express the
desired style rules using XSLT/FO which is far more documentatble
as a language than "random tex hacks" as used to write a normal tex
package, and secondly that that same style specification might be used
by a completely different engine formatting to some unknown format.

If that's all you want, true just write the html directly.
But why can't I specify a general layout scheme for my online doc in
xsl/FO then produce pdf, dvi, html+css, or some new hypertext system
all from the same spec?
