To elaborate by example:

<?xml version="1.0"?>
<foo><script>if (a && b || 5 < 6) alert("Hi!")</script></foo>
                   ^---------^-------- ILLEGAL CHARACTERS

<?xml version="1.0"?>
<foo><script><![CDATA[if (a && b || 5 < 6)
alert("Hi!")]]></script></foo>
LEGAL!


<?xml version="1.0"?>
<foo><script>if (a &amp;&amp; b || 5 &lt; 6)
alert("Hi!")</script></foo>
LEGAL!
