The main element is an exact analogue of ARIA's role="main", and is designed to show screenreaders and assistive technologies exactly where main content begins, so it can be a target for a "skip links" keyboard command, for example. It could also be used for content syndication (Instapaper-ish things) mobile browsers could zoom in on main when encountering non-responsive websites.It should therefore be used once per page. If you use something like(or similar, such as ), simply replace that with .
