I don't think the intent is to get all legacy content using
role="presentation" it is to promote the use of a standard generic mechansim
for elements that should not be exposed via the accessibility API. the use
on <img> being one example.

i think that it would be appropriate to add a user agent requirement that an
img with empty alt should not be mapped to accessibility APIs as this is
what it how it works in AT.

as far as the warning goes i can live with it not occuring.
