Hi Silvia,

Will do. Thanks.

That's what is needed.

Some sighted people may be aided by access to a longdesc. Browser
vendors should provide access to those who want or need access.

It might help. Authors can do that. Not many do.

I don't have a  sample on the User Agents and longdesc Discoverability
page [1], but in some implementations (an on-page description revealed
below or alongside an on-page image) it could be redundant.

Thanks for your thoughtful comments, Silvia.
