I have added another page named
http://www.cwdjr.info/extensions/autoForceXhtml.php .
It is designed to automatically force the page to be served as
application/xhtml+xml no matter what the browser says it will support
or likes in the header exchange. Thus browsers that really will not
support true xhtml 1.1 served properly will not display the page.
However if there is a "xhtml ready" browser out there that really could
support true xhtml, but does not because it does not mention it in the
browser-server header exchange, this page may smoke it out. I give more
discussion on the page if your browser allows you in. This new page
gets in and displays for the recent Firefox, Netscape, Mozilla, Opera,
and W3C Amaya browsers. It does not open the page for IE6 or Netscape
4.8, which of course it should not. Of course I do not know if there
are really any "xhtml ready" browsers out there, and if there are I do
not have them installed on my computer.
