Comment 1: Progress Bar
Source: http://lists.w3.org/Archives/Public/public-comments-wcag20/2008Feb/0152.html
(Issue ID: 2591)
Original Comment:

Just to clarify. Is the progress bar, which shows the status of the
progress with the animation, "part of an activity where the changes
are essential"? Should it be stopped within 3 seconds or have "Pause"
and "Restart" button?

Response from Working Group:

We have added a definition for essential to help clarify this:

 if removed, would fundamentally change the information or
functionality of the content, and information and functionality can
not be achieved in another way that would conform

The purpose or function of a progess bar is to show the time-based
progress of some activity, so it would be essential.

Success Criterion 2.2.2 also says that "Moving or blinking content
that is pure decoration can be stopped or hidden by the user." If
there are aspects of the implementation of the progress bar that are
purely decorative, such as flying files, some method needs to be
provided to pause and restart, dismiss or hide the decorative movement
for users who find it distracting.
