Re: Auto-WCAG vocabulary

Hi Hilera,

Thank you for this excellent suggestion. I like it! I have been looking at
an update to our rule structure for the next meeting. We've already
discussed breaking the results out from the test steps and put them in a
separate section. I think this is a great addition to this. I'll have to
look at maintainability. EARL isn't the easiest thing to write. But I'll
have a look, and I'll have the proposal ready for the next Auto-WCAG call
(next Thursday). You're welcome to join us. I'd love to get your take on it!
