Focus on Date/Calendar accessibility
I'd like to post a focus on Date/Calendar modules accessibility.
Following mgifford's comment on a Calendar issue regarding accessibility I'm posting here some issues for that modules that would need some love/reviews from users who cares about accessibility.
I'm talking about:
- Calendar: Accessible calendar navigation thoughts providing a "caption" for calendar table
- Date: More accessible date navigation with prev/next and month link-titles
- Calendar: accessible calendar block adding 'abbr' for days in calendar table headers

Whatever the date / calendar
Whatever the date / calendar solution ends up being, the best approach would be to use progressive enhancement with WAI-ARIA. A calendar or date widget is exactly the type of complex control that would benefit from ARIA, provided that it is designed in a way that gracefully degrades.
