This is a wonderful way to generate XML schema file or even DTD file
using TD :) Anyone feels like hacking that in? ;)

I've just committed a patch for the xml_decl sub but the API is now a
bit more general.

For instance,

    xml_decl { 'xml', version => '1.0' };
    xml_decl { 'xml-stylesheet',  href => "chrome://global/skin/",
type => "text/css" };

will produce

    <?xml version="1.0"?>
    <?xml-stylesheet href="chrome://global/skin/" type="text/css"?>

To be honest, I'm not very happy with this way of specifying XML
namespaces since it's not flexible enough. I'm proposing using Perl
packages to emulate this kind of things. For example, html::div { ...
}, but we need to define the html package and import symbols into it
ourselves (sort of).
