Re: In WCAG NEXT let's put a date field on failures

Careful — if you do that you may destroy the technology independent nature of WCAG  — and you make it list based - which makes it always out of date

1) list based 
WCAG currently covers all information provided visually…..
if you change it to  headings and lists and this and that — then you will always have an incomplete list and the rest is not covered. 
WCAG says “all" - and then explains what is included (but not limited to ) by the word ‘all’ in the Understanding WCAG 2.0  doc.  You can say   " including but not limited to “ in understanding but not in a standard provision. 

2) technology independence.
if you specify headings need to be x — you are usually referring to constructs in HTML that may not exist elsewhere.   Again WCAG leaves technology specific terms to ‘sufficient techniques for specific technologies — rather that making WCAG tech specific
Now many technologies may have headings — but they may call them by other names — or there may be other things in addition. 

I think all of the things you seek below are covered and required by WCAG already.      breaking them out in WCAG instead of Understanding WCAG 2.0  can create the problems above.

if the problem is that people don’t know that they are covered - then Understanding WCAG 2.0  can do that without needing to change WCAG and risk the above issues. 


Just saying to think it all the way through before changing the model.   The WG spent a LOT of time (years) trying to make it clearer and more specific without tripping these other issues.   It is REALLY hard. 

Good luck

Others support associations of objects (table headers, and table data) as well as labels and controls 1.3.2 could be interpreted as an SC under 1.3.1 e.g. sequences can be programmatically determined. Separation of style from meaning really seems like the core guideline, not the more vague, flexible data.  It gets at the relationship between markup language and accessibility.
