Hi all,
If an image has a role=presentation and a non empty alt, shouldn't the alt
text be passed to AT?

example:

<a href="home.html"><img src="home.gif" alt="home page"></a>

currently this typically results in a screen reader announcing:

"link graphic home page"

when the presenece of the role information seems less than useful in
context.

if role="presentation" allaowed the text "content" of the image object to be
passed to AT then

<a href="home.html"><img src="home.gif" alt="home page"
role="presentation"></a>

would result in the follwoing being announced:

"link home page"

currently this does not work as adding role="presentation" removes the image
form the browsers accessible tree.
