Sounds like one of my two year old son's tantrums.

Just out of interest, where did you get the idea that these lists are
here to serve you individually? As it happens, I think your question
has been answered pretty clearly, and it sounds to me more like you
disagree with the answer, rather than it hasn't been answered.

I'm sorry that you disagree, but hey, that's life. If you're going to
throw a tantrum every time you don't like the answer to something you
might be better off avoiding these lists. I certainly don't think it's
reasonable behaviour to get rude and throw your toys out of the pram.

Anyway, let's get back to your issue since it's sure to affect other people.

That is an example of using <noscript>, that's true, but there is no
*need* for this. Your use of document.write() is to create something
in the document that would only be accessible to someone who has
script enabled, but that can just as easily be done like this:

  <html xmlns="http://www.w3.org/1999/xhtml">
    <head>
      <script type="text/javascript">
        function jssupported()
        {
          var oEl = document.getElementById('jssupported');

          oEl.style.display = "block";
          return;
        }
      </script>
    </head>
    <body onload="jssupported();">
      <div id="jssupported" style="display: none;">
        <!-- put stuff in here that requires script -->
      </div>
      <!--Jasper's NOOP-->
    </body>
  </html>

Note that this is completely generalisable, and easier to maintain
than lots of document.write() statements. It also works in the HTML
'incremental loading' model, as well as the XML->XHTML model I
described earlier.

There are plenty of other ways this could be done, but the key point
is that we therefore don't *need* the <noscript> element in an *XHTML*
browser.

I would say that it *was* needed in an *HTML* browser though, since
you might have this:

  <body>
    <p>Hello Jasper, welcome back to your online banking.</p>
    <script ...>
      document.write("Your balance is:" + nBalance);
    </script>
    <p>Hope that helps.</p>
  </body>

In this situation the *initial* appearance of the document will be
different, depending on whether you have script enabled or not, and so
there is no other alternative but to have the <noscript> element. This
is not the case in XHTML, since there is no equivalent of
document.write() modifying the document as it is loaded.

Mark
