From http://forums.whatwg.org/viewtopic.php?t=38I can extract two requests.
Another now (post #193):Make <noscript> allowed in XHTML5, and generally remove differences between HTML5 and XHTML5 where possible.
This could thus also imply: * Don't disallow lang="" in XHTML5 * Don't disallow <base href> in XHTML5.* Don't disallow <meta charset> in XHTML5 (it doesn't do any good, but doesn't harm either).
