It is possible to work around that with OpenSP.  See for instance
http://valet.webthing.com/page/val.cgi?url=http%3A%2F%2Fwww.oxnardcc.org%2F%7Embowen%2Fanswers%2Fsf5ch01test2.htm&input=on

Unfortunately the current Page Valet seems to have reintroduced
the same problem as the W3 validator :-(

Current work-in-progress is aiming that way.  I have run a prototype
with Xerces-C++, but it's some way off robust enough to go public.
