Gregg and Lisa,
For reference we are talking about this list: https://www.w3.org/WAI/GL/wiki/WCAG_2.1_Success_Criteria
#8 reads (including the prefix):
Success Criteria shall avoid creating a requirement for something that is already required by an existing Success Criterion.
I think that your suggestion is fine in that we are already indicating that a level change is acceptable with #5 (Ensure for revised Success Criteria that pages that meet the revised guidance continue to meet the corresponding WCAG 2.0 Success Criteria).
I think that perhaps the solution is that we just add “(Level changes are not regarded as new requirements)”. Thoughts?
Thanks,
AWK
