Abstract:

HTML is hot again. Some time ago the HTML5 promo machine got up to speed, causing a little mini-fuss. In a parallel universe, others are still putting a lot of time and effort into the development of xHTML2. This (public) renewal of interest in HTML caused plenty of discussion, revealing several blank spots in the general knowledge of HTML. This article will hopefully plug one of the most notorious holes shut.
