At least in Gecko, we parse the contents of <noembed>, <noscript>, 
<noframes>, and <iframe> as CDATA when we're not going to be using their 
contents because in the past, we've had lots of problems with authors 
treating these tags like C's preprocessor directives, handling cases 
like: <head><noscript><body>...</noscript><script>...</script><body> is 
extremely difficult (and then preserving round-tripping for editor gets 
to be a problem, and the list of problems goes on).

By treating the contents of these tags as CDATA, we're able to make most 
people happy (though nesting <noscript>s doesn't quite work as expected).
