Hi Matt,

Simple question: why letters? We have level 1, 2 and 3 checkpoints that
directly correspond to the level of conformance, what would be easier than
just using these numbers for conformance levels as well? You would have
level 1, level 1+, level 2 or level 3 conformance. You can even have level
2+ if you want. 

Extra benefit: less confusion with WCAG 1. Handy since level AA WCAG 2
covers more (in my opinion) than level AA WCAG 1. Using a different system
makes it clear that different criteria are met.
