Seizures: This is a Level 3 SC yet the Intent specifies that it is intended
not to cause seizures.

Proposed Change:

Clarify the SC. If it is intended not to cause seizures it should be at
Level 1.

Response from Working Group:

The primary seizure provision is already at Level A.  This provision is an
extra measure that can be taken for those who want to go above and beyond.
It covers all flashing including very small areas of the screen that would
not be sufficient to cause problems.  The purpose is to allow users to use
extreme magnification and still not have a problem.  This goes beyond all
current standards.
Response from GSW:
I am happy for this to remain at Level 3 - I trust that the WG has
sufficient research to back this up - however my comment actually pertains
to the use of "preventing seizures" as an intent. If WCAG2 has a SC in Level
3 that is intended not to prevent seizures then I am sure there will be
questions in the larger web community as to why it is at such a high level.
I understand why it is there and accept that it is the proper position for
it (assuming there is research behind this) however just saying "to prevent
seizures" doesn't explain why this is at Level 3 and not at Level 1 - like
Checkpoint 7.1 was in WCAG1. I would recommend removing this intent or
clarifying that it builds on previous SC and that those previous SC are - in
most cases - sufficient enough to prevent seizures.
