Sorry but you do not need CDATA sections, they are only syntax sugar so
you can write

  <script><![CDATA[ if (a && b) ... ]]></script>

rather than

  <script> if (a &amp;&amp; b) ... </script>

and again, XML is not stricter than SGML in a sense that would seem
relevant here. Where did you get this from?

Again, there is nothing non-conforming about my example, the <a> element
may have <script> content and text content and "+ADw-script+AD4...script
code...+ADw-/script+AD4" is legal in both UTF-7 and UTF-8. Why do you
think there is any error in my example?
