In HTML, <script> and <style> are defined as containing CDATA, so <!--  
is a string of characters and not the start of a comment (and magic  
happens to stop them being interpreted as CSS or JS). There is  
something to render here.

In XHTML, <script> and <style> are not defined as containing CDATA, so  
a comment is a comment and stops the script from being executed  
(assuming the document is not served as text/html). There isn't  
something to render here.
