My understanding is that W3C considers UAAG an example where RFC 2119
keywords are not good enough. See authors comments quoted by Lofton.

Also, please do not mix the question of whether to use RFC 2119
keywords with a question whether keywords must be in caps. I disagree
that specs MUST use RFC 2119 (I think they SHOULD). I agree that
requirements MUST be programmatically identifiable (without AI
techniques).

This is a strange argument. If we accept "didn't know it was a
requirement" as an excuse, there is no reason to write SpecGL at all.
SHOULD and MUST have about the same visibility and about the same
probability of being unknown due to poor communication. By making this
requirement a SHOULD we gain uniformity among most specifications and
flexibility for truly exceptional specifications.
