Alistair,

 

I get your point. Hmmmm…

 

The problem is I *thought* we were not going to change the existing SC, and that this was clearly indicated to the TFs when proposing new SC….:-(

 

Boy this is one reason it would have been nice to have *clearly defined* as a requirement (and again, I thought it was). Add to the lessons-learned department….

To be backwards compatible it looks as if the new content they suggest for an existing SC will have to became a new SC related just to the specific changes.

 

This would sort of go along with the idea that each new SC should have - and then test – very distinct criteria.

Hi Katie,

 

That isn’t the situation for many new SCs, the impact of that approach is that either:

-          None of the ‘increased’ requirements can make it through to 2.1 (including many from COGA), or

-          We will have duplicate (raised level) or severely overlapping SCs.

 

For example (from a quick skim, there are probably more):

https://github.com/w3c/wcag21/issues/56

https://github.com/w3c/wcag21/issues/51

https://github.com/w3c/wcag21/issues/40

https://github.com/w3c/wcag21/issues/33

https://github.com/w3c/wcag21/issues/32

https://github.com/w3c/wcag21/issues/29

https://github.com/w3c/wcag21/issues/22

https://github.com/w3c/wcag21/issues/13

https://github.com/w3c/wcag21/issues/7

https://github.com/w3c/wcag21/issues/77 

 

All of those will either overlap *a lot*, or they can’t go into 2.1.

 

NB: I had raised this previously [1], but it wasn’t really the time to discuss it as the SCs weren’t close enough. Now they are.

 

What I’m saying is that if a new SC is “Good” (meets the SC requirements apart from overlap), then we tackle each case, analyse the understanding, techniques & failures docs, and if it can be done in a backwards compatible way, update the existing SC.

 

Cheers,

 

-Alastair
