Ok, done. I also removed the <!--/--> stuff from RCDATA and RAWDATA elements, and made it so that you needed the right characters after <script and </script to go into the inner-escape mode, so that <scripting> didn't trigger it also. This also made the conformance requirements for <script> quite complex. I ended up using ABNF, but I couldn't quite work out how to do it without prose rules. If anyone can rephrase the ABNF for <script> restrictions without using prose rules, please let me know. (Also acceptable: a version of the ABNF in unambiguous English prose. I didn't even try in this case because I think it would be inpenetrable.) -- Ian Hickson U+1047E )\._.,--....,'``. fL http://ln.hixie.ch/ U+263A /, _.. \ _\ ;`._ ,.
