Re: [w3c/wcag21] Popup Interference (#75)

Hi Jim, Wayne, Marla, and all,

We will likely need a definition for the word "obscure". Maybe use or
tweak UAAG's definition? [1] It is:

"To render a visual element in the same screen space as a second
visual element in a way that prevents the second visual element from
being visually perceived."

Do we want to expand that to include use cases other than just the
"same screen space"?

The term "important information" is already listed in the 2.1 terms
[2] so we can just link to that.

Questions that will likely be raised and for which we should be
prepared to answer:

* What is the technique to turn off the informational content? Do
authors need to provide a mechanism?
* What are the other means of accessing the informational content?
* Others?

I would suggest removing the note as authors can indeed solve the
title attribute issue in 2.1 with Marla's techniques [3].

Kindest Regards,
Laura
