Yes, presumably in the section defining ARIA role mappings.  See below.

Yes, of course they would be allowed.  I never suggested otherwise.

The current spec already maps <header> to the banner role, but the 
definition needs to be refined as described.

The spec also maps <footer> and <address> to the contentinfo role, but I 
don't think the spec needs to change anything here, at least until ARIA 
does restrict contentinfo to just one element, if they do as Steve 
suggested.
