Re: aria vs native alternatives [was: Re: feedback requested on WAI CG Consensus Resolutions on Text alternatives in HTML 5 document]

hi henri,

the spec states:
WAI-ARIA processing by the user agent *MUST NOT* interfere with the normal
operation of the built-in features of the host language.
If there are no keyboard host language navigation features for say a div
element, but a landmark role added to the div is used for navigation,  how
is the use of ARIA intefering?

 How would you suggest the spec be changed to allow the use of ARIA
landmarks for keyboard navigation?

do you also consider that the use of aria attributes as CSS styling hooks to
be an issue as well?
