RE: A Guide to the "Essential" survey

All of WCAG 2.0 uses “essentia’” as an exception in only 4 success criteria (and 1 incorrectly in “No Timing”).  In 2.1, we’ve introduced it 11 more times (half of the new criteria).

[Jason] This result tells me straight away that more work is needed. WCAG 2.0, as it stands, has already inspired concerns about reliable testability; making liberal use of terms such as “essential” and synonyms thereof (otherwise than in accord with the WCAG 2.0 definition of “essential”) would make those problems much worse, not better.
I agree with Steve that each case needs to be analyzed and appropriate changes made.
