as per the current tables in the html5 spec if an element has no
restrictions placed on it in regards to its role, the element is not
included in either table.

#I will add a list of elements that have no restrictions to make this
explicit.


>Where do we call out global ARIA attributes? - these can be used anywhere
per the ARIA spec.
As far as aria-* attrubutes are concerned all are allowed on any element
unless otherwise stated.

#I will make this clear as well.

>Developers can override this with script. So, I would suggest that we allow
aria-haspopup on these. That raises another issue. >This proposal states
that aria-haspopup only refers to a context menu. That may not be true. It
could be a submenu reference.
 see preceding comment.

will ad nav to section
the main restriction is as per the aria spec.

>What happened to <th>? It should have a default role of either columnheader
but can be overriddent by rowheader or >columnheader

its in table 1

>footer has a default role of contentinfo. If you recall Ian or someone said
footer has no defined location.
this mapping is taken from the current html5 spec text.
