Re: Combine 79, 78, and 74 SCs? (was Re: Mechanism Disclaimer)

Hi Gregg,

Thank you for your Email and questions.

It has been reported by Jim Allan and members of the Low Vision Task Force
(LVTF) that Acrobat DC and VIP PDF Reader provide support.

The level is an open question and has been debated. We don't have consensus
yet on that point. All 3 of the original SC levels were submitted at AA.
Most commenters on Github would like AAA. At least one person from the LVTF
stated it is a solid AA for many people.

There has been discussion in the LVTF to have an exception for UAs that do
not provide support. Hence Wayne's mechanism disclaimer thread.

As for techniques Alastair is working on a solution ala his bookmarklet.
Wayne has proposed: "Never use !important for online settings..." PDF
techniques haven't been discussed. Perhaps Jim could add that to Thursday's
LVTF agenda?

Thanks again.

Kindest regards,
Laura
