No more predefined classes in HTML5
Just announced on the HTML5 working group mailing list, predefined classes are now removed from the official spec.
"In response to overwhelming feedback on this issue (especially in blogs, forums, and mailing lists other than this one, like www-html and public-html) I've removed the predefined classes. They're opaque again."
