Re: Extension conflict/compatibility requirement

Thanks Laura,

This is very helpful

Here it the problem/question I am having with the use of the word  Success Criteria 
I looked over the document and I saw lots of techniques and general advice — but nothing that would qualify as a success criteria. 

A success criteria would be a testable statement about the Web content - that can apply to all web content (as qualified in the SC). 


For example

“Use a clear structure”  
is advice (or a command)  but not a success criteria.
as a success criteria it might be worded  “Content uses a clear structure”  
except that isn’t testable.  
What does clear structure mean exactly for all types of content?
Would most everyone agree for each page whether the structure was clear or not?  
If not it can’t be a criterion for success. 

I love the document — it is full of great techniques and can provide a lot of valuable guidance in how to make things more accessible to not only people with cognitive disabilities but everyone.   
But I think you are running into the same problem that the WCAG WG ran into with WCAG 2.0

There are lots of things to talk about or provide advice on.    But there is little that 
a) applies always on all web pages   (including the National Science foundation,  medical websites,  an online physics course,  the online repair manual for a nuclear resonant imager, etc. ) or else have clear unambiguous criteria for what is excluded from the requirement) 
b) is objective enough to be testable  (most people rating something independently would come up with the same answer) 

This is what drove us crazy in trying to define SC in this area and find thing that there was consensus on as being  testable, and applicable across we pages.   (These arent the only criteria for SC but they are the ones that stopped us the most. 


Maybe I missed one or two in the document — that would qualify (if I did let me know) .     But most (or all?)  of the things listed as SC  - can’t qualify.     

They are all good advice.  But not


I think it is important to not label things as SC that don’t qualify.   It really confuses the discussion - and will only create stuff that needs to be reworked later.  


PS - I also saw that some provisions were recommended to be moved from level AAA to higher levels.   The one exception we did make (in order to include more cognitive SC) was to put some things into Level AAA that did not apply to all web content.  We clearly mentioned that in the WCAG (that some things in level AAA could not be applied to all websites) and recommended that level AAA never be universally required for that reason.    For that reason - those items also could not be moved to higher levels because they do not meet the full SC criteria. 


Good luck on this.   This is a critical area — but it is very hard to find things that qualify as SC.    I think a better route is to focus on creating a “Design Guidelines for making web content more accessible to people with cognitive, language, and learning disabilities”     and make it a ‘how to’ rather than a standard - which will just tie you up in knots like it did the WCAG WG working on WCAG 2.0 — because a standard can only have objective testable criteria  for conformance — and ones that always apply (or always apply as qualified) —  and we  don’t know how to do that for most all of the good advice that we have for making things accessible to this important group of groups of users.
