[whatwg] Script, style and backwards compatibility

[Simon Pieters]

 From http://forums.whatwg.org/viewtopic.php?t=38

I can extract two requests.


1. Explain how authors are supposed to "comment" their <script> and  
<style> elements in HTML5. (Post #171.)

Something along the following lines could be inserted as a note in the  
syntax section, e.g. after the "CDATA elements can have text, ..."  
paragraph:


    Old browsers that don't understand the style or script elements
    (introduced in HTML 3.2) will attempt render their contents. However,
    the strings "<!--" and "-->" are part of the CSS syntax, and "<!--" is
    equivalent to "//" in JavaScript, so authors who don't want to reveal
    their style sheets or scripts to users with such browsers can simply
    comment them out. [CSS21] [ECMA262]

       <style>
       <!--
       ...
       -->
       </style>

       <script>
       <!--
       ...
       //-->
       </script>


(But it is an issue though that ECMAScript 262 still doesn't define the  
<!-- magic.)


2. Explain how HTML5 and XHTML5 differ in practice. (Post #187.)

e.g. something like http://wiki.whatwg.org/wiki/HtmlVsXhtml could be  
included as a non-normative appendix to the spec, or referenced to in the  
HTML vs. XHTML section, or similar.
