Re: Principle 4 - Robust (was Re: Help needed with numbering success criteria for WCAG 2.1)

Hi Jason,

I'll focus on the snippet "This may include Web browsers, media
players, plug-ins , and other programs — including assistive
technologies..."

By the inclusion of "This may include" it is clearly indicated (to me) that
this is not an exhaustive list, and that "User AGent" can and should also
consider hardware peripherals as part of the stack (i.e. a Braille output
bar), and here, perhaps the device itself (a mobile device).

Personally, I've always given the widest of understanding to 'user agent'
as "the stack" of hardware and software tools that allows any individual
the ability to connect to and access the web. As well, while the definition
you provided is taken from WCAG 1.0, we're now discussing WCAG 2.1, and so
I'll suggest that if we agree on the "full stack" definition I mentioned,
and we are currently working on WCAG 2.1, that we look to ensure that an
updated definition also emerge.

I'll return to Patrick's comment: "Certain user groups cannot change the
orientation of their device (think for instance fixed mounted tablets on a
wheelchair).", and so I honestly believe this *is* a real issue that WCAG
2.1 should address - it may not be 100% "content", but it is a web
accessibility issue that is directly created (or not) by the page author
(which is what makes it in scope to me).
