And such images are rare on the internet. We can't use data about all
the image to check if complicated ones are accessible.

Reading that, I wonder if the nature of the target element by the
longdesc is not a little bit underspecified. If i indicate for a Mona

is it still usefull for screen readers ? Perhaps the linked page
should only contain the longdesc and no menu, footer, ...
