  1. XHTML doesn't have decrement operators!  

    Are you using PHP or JavaScript?  These languages do allow decrement operators, but by the time they produce XHTML output, the decrement has already happened.  

    If you've embedded JavaScript directly in your page, XHTML validators sometimes get confused.  Use the CDATA directive to tell the validator to ignore JavaScript:

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"

    "http://www.w3.org/TR/xhtml1/DTD/xhtml...

    <html lang="EN" dir="ltr" xmlns="http://www.w3.org/1999/xhtml">

      <head>

        <meta http-equiv="content-type" content="text/xml; charset=utf-8" />

        <title>HelloWorld.html</title>

        <script type = "text/javascript">

          //<![CDATA[

            // Hello, world!

            alert("Hello, World!");

          //]]>

        </script>

      </head>

      <body>

      

      </body>

    </html>
