Bruce Lawson’s personal site : Scooby Doo and the proposed HTML5
Bruce’s thoughts on the proposed inclusion of a “content” or “maincontent” element in HTML5.
Personally, I don’t think there’s much point in adding a new element when there’s an existing attribute (role=”main”) that does exactly the same thing.
Also, I don’t see much point in adding an element that can only be used once and only once in a document. However, if a “content” or “maincontent” element could be used inside any sectioning content (section, article, nav, aside), then I could see it being far more useful.
