Re: Rough draft of some success criteria for a extension guideline "Touch accessible"

>2.5.1 Touch: All functionality of the content is operable through touch
gestures. (Level A)

Suggested friendly amendment:

2.5.1 Touch: All functionality of the content is operable through touch
gestures with and without system assistive technology activated. (Level A)

I think this will address my concern that often touch gestures don't work
when VoiceOver is activated.


Cheers,
