from reading the spec we concluded that details may have a default role of
button as it is likely to be the element a user will interact with to show/hide
the details content.


> input type=file - changed from "button" role to no role

in the majority of cases this is a composite control consisting of a button and
a text box. refer to
www.456bereastreet.com/archive/200410/styling_even_more_form_controls/ for
example browser rendering of this control.


> link (that represents a hyperlink) - changed from "link" role to no role

as it is one of the meta elements and not generally included as part of the
page content we consider it to be out of scope for ARIA.


> menu type=context - changed from no role to "menu" role
its a menu

> output - changed from "status" role to no role
its not a role=status its may be a generalised live region.

> math - changed from no role to "math" role

role="math" will map to a math role in Accessibility APIs (if they have one) We
think the <math> element will also be mapped to a math role in APIs

> table - changed from "grid" role to no role
 role="grid" is an interactive table, a table by default is not interactive.

> td - changed from "gridcell" role to no role
role="gridcell" is an interactive cell, a cell by default is not interactive.

> tr - changed from "row" role to no role

"Rows contain gridcell elements, and thus serve to organize the grid."
