This page lists the allowed extension values for the class="" attribute in HTML5. You may add your own values to this list, which makes them legal HTML5 class names. We ask that you try to avoid redundancy; if someone has already defined a name that does roughly what you want, please reuse it.

== "description" meta name ==
I think the description name should be added to the HTML 5 specifications. Yes, search engines have made the keywords name obsolete. However search engines are not ''that'' good. It is still only the document author that can provide a reliable, short description of the documents contents. I think there should be constrains on how long, what it contains, and the structure of the description. Short sentences, and plain English descriptions would be the best.
