But (and I'm not trying to be antagonistic, just trying to make a decision),
why doesn't this restrict XSL-FO to being just a cute example of an XML
application? If by using TeX, people can get the power of PostScript without
sacrificing XSL-FO's high level formatting features, then why wouldn't TeX
be the proper solution for their problem? Even if XSL-FO is fully device
independent, a TeX/PS solution isn't exactly device specific.

So to sum up the argument so far:

I asked why we should prefer XSL-FO over PostScript, since PostScript is
more powerful. The reply was that PostScript didn't have the high level
document features provided by XSL-FO. So now my reply is, TeX provides
those high-level features, *and* it allows PostScript constructs that
give the full power of PostScript to the user. Is there another reason
to prefer XSL-FO?
