Re: Comments on proposed new SC 2.5.3

How about this? I managed to remove the redundant mention of up-event, and
was able to keep the conditional nature of it...

2.5.3 Up-Event Activation: When single touch and/or pointer activation is
triggered, then at least one of the following is true (Level A):

​- ​
Activation is on the up-event
​- ​
Confirmation is provided which can dismiss activation; or
​​- ​​
Activation is reversible; or
​​- ​​
A mechanism is available to allow the user to trigger activation on the
up-event; or
​​- ​​
Timing of activation is essential; waiting for the up-event would
invalidate the activity.

Note: This is when platform assistive technology that remaps touch gestures
is not turned on.
