It's mostly been this way just because it was easiest, and we were defining
the namespace which was getting embedded into the message packet. It doesn't
have to be this way :) Basically, the root element being embedded must be in
the namespace which is being defined. So for example, putting xhtml into a
message uses the <html> root tag, since thats what the namespace defines. So
an XHTML message packet looks like:

<message>
  <body>hi</body>
  <html xmlns="http://www.w3.org/1999/xhtml">
    <body>
      <h1>hi</h1>
    </body>
  </html>
</message>

When the JSF is defining the actual namespace which is getting embedded into
the message, the common "convention" is to use the x tag, but the namespace
is really what matters.

Hope this clears up the confusion.
