You can get to it from <URL: http://www.w3.org/TR/ >,
under the heading "Recently Published Working Drafts".
WDs for XSLT 2.0, XPATH 2.0, and XQUERY 1.0 were just
added today (20 Dec 2001).

CSS and XSL-FO have very different architectures though.
CSS is all about annotating existing XML documents
with just enough presentation information to display them
in a Web browser (with support for other media like paper
added later), whereas XSL-FO is an XML representation
of an abstract model for typesetting documents (with support
for other media like Web browsers added as an afterthought).
There are some applications where XSL-FO is more appropriate
than CSS and vice versa.
With XQuery though, there's almost nothing in there that hasn't
been added to XSLT and/or XPATH (except perhaps the syntax, which
is rather more pleasant IMHO).

ISTM something like this would be really useful for XPointer.
XPath 2.0 is *way* overkill. I think a good approach would
be to start with TEI XPTRs and take stuff out.
