[Bug 21565] Should it be an error to use @longdesc on presentational images? And/Or should it _affect_ the role of the image?

--- Comment #5 from Leif Halvard Silli <xn--mlform-iua@xn--mlform-iua.no> ---
I have no idea about what to say about the search engine use case. But else, I
would like to suggest something like this for the spec:

 ]] 
   With or without @longdesc, this spec, in accordance with HTML5
   and ARIA, expects UAs & ATs to look at @alt or @role in order
   to decide whether to present img elements to the user at all.
 [[

PS: May be it would also be be worth verifying that longdesc on presentational
images does not confuse users of legacy AT that support longdesc?

For example: I *think* e.g. Jaws will just ignore such images unless the user
somehow decides to inspect presentational images. However, it is very long time
since I checked it out.

It would seem unfortunate, to me, if legacy versions of Jaws actually announces
the longdesc link even if the image has an empty alt.
