Hi Gregg,

Firstly, I agree with your proposal to remove L1SC1from 3.2.

I also agree that a change of content is different from the current
definition of change of context. This is relevant to my success criteria
(When any component receives focus, it does not cause a change of context),
where focus given to a menu item may cause a sub-menu to be displayed.
That's obviously a good thing, and shouldn't violate this success criteria.

I do have concerns about change of content with remote scripting techniques
(which seems to be the new black), as that can cause accessibility problems.
This is more relevant for L2SC3: Changing the setting of any input field
does not automatically cause a change of context. If a change of content
isn't the same as a change of context in this instance, then we're saying
that it's okay to dynamically update portions of a page in a way that could
be missed by some assistive technologies. I wonder if it would be worth
adding another success criteria (possibly level 3) that deals with changes
made using remote scripting, as I can't see anywhere else in the guidelines
that covers this?

Best regards,
