It's technically already allowed because script and style elements are defined to contain CDATA. So basically any string of text that doesn't include '</' before the end tag is valid. It's already interoperable because that whole string is passed to the javascript engine, and since the '<![CDATA[' and ']]>' are commented out with javascript comments, they're ignored. For more information, see http://lachy.id.au/log/2005/05/script-comments > But it seems somehow stupid to define that <![CDATA[ and ]]> are only > allowed inside <script> after "//". There is nothing to define beyond what is already in the spec. Just like <!-- and --> isn't a real comment inside an HTML script element, that isn't a real CDATA section. Only Opera (AFAIK) even implemented support for CDATA sections in HTML. So although that may suggest that they can be supported by browsers without breaking anything, their use wouldn't be backwards compatible with other legacy browsers, so they have to be forbidden. -- Lachlan Hunt http://lachy.id.au/
