the web pages will be preprocessed before the are put on the server
(this transparently happens upon checkin) and as part of that

  <?xml version="1.0" encoding="ISO-8859-1"?>
  <!DOCTYPE html
            PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
            "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

are going to be prepended to any page, plus the standard CSS reference
and footer are added, for example.

Since you ran into this, I would like to document this better.  Would
http://gcc.gnu.org/projects/web.html be a good place, or do you have
a different suggestion?
