hi maciej,

(unlike, say, <input type="button">).
This is really incidental to the issue being discussed, most, if not all
html elements can be scripted and styled in a way that overides their native
semantic
If this is allowed, then it follows that the addition of ARIA roles
should not result in a conformance error, as the addition of ARIA is
incidental to the developers intention to overide the native semantics. If
the addition of scripted behavior and styling to overide element
semantics is a testable conformance error in HTML5 then I would agree that
the addition of an ARIA role should also be, my understanding that it is
not.
