This is very good data and a great list of sites that support longdesc
for their accessibility needs. I have always admired your excellently
prepared data and the excellent work you've done for the TF, so I am
really sad to see you go.

Interestingly, you data actually confirms the message that I just sent
on another thread [1] about moving to @aria-describedat. I would think
that all of these institutions that are supportive of accessibility
and are using @longdesc in the correct way for this purpose would
accept moving to use @aria-describedat if we encouraged them to do so.
In this way, the vast pollution of @longdesc values that we see in the
wild would be replaced by only clean and accurate use of
@aria-describedat . It would make it easier for tools to identify
sites that have appropriate and usable long text alternatives, since
you can just search for @aria-describedat and know you will get good
results, rather than searching for @longdesc and having to wade
through vast numbers of misuses.

Thanks again.

Regards,
Silvia.
