The XSL 2.0 requirements document is at http://www.w3.org/TR/xslfo20-req/

I've noticed that in the recent announcement emails, and here, that
it's "XSL 2.0" in the title, but then "XSL FO" everywhere else..
including the url.  Even in the abstract is says "This is the
requirements document for XSL-FO and not for XSLT", which would be
obvious if was just called "XSL-FO" all the time....

Is there a reason why it can't be referred to as "XSL-FO" whenever you
mean XSL-FO?

 After the split, XSLT emerged, XSL-FO kept the XSL
as the WG name etc.

I guess XSL is the WG, so it must remain, but XSLT and
XSL-FO are the two recs in reality.
