Re: What if Silver didn't have levels?

I don't think that setting a level somewhere on the scale is a good 
idea. As soon as we do that, we validate the question "what is the least 
I have to do here?", and as soon as that happens we've accepted that 
some people will be disadvantaged. In other words we create a class system.

If we instead set the "level" at 100%, we solve this problem. It also 
makes the definition of "accessible" a lot easier for people to 
understand - whether you're in court or implementing a new interface, 
people understand that 100% is the most you can achieve.

I think this single "level" becomes even more important if we think 
about bonuses.

A problem with bonuses is that if they're awarded for meeting additional 
requirements, it effectively reintroduces the levels problem. We know 
this from all the Level AAA requirements that are never met.

But if we offer bonuses for meeting requirements in ways that are known 
to be superior, or in ways that offer a better UX, I think we can 
protect against this risk too.

For example, there is a requirement to provide captions for multimedia 
content, and it's worth 1%. If you make it possible to adjust the 
location of the captions, that gets you a bonus 1%.

Please don't get into the weeds of discussing this example. It almost 
certainly won't stand up to the tiniest bit of scrutiny. It's just meant 
to be an example to illustrate the idea.

I'm also wary of the idea of "grandfathering" WCAG into the Silver 
model. As soon as we say that X point on the Silver scale is the same as 
Level AA, we implicitly reintroduce the class system I think is such a 
terrible idea. We transitioned from WCAG 1.0 to 2.0 without any real 
mapping between the two, and so I have no reason to think the same thing 
can't happen when we transition from WCAG2.x to Silver.

I think it's worth looking at the inversion model Alastair mentioned 
though. Instead of starting at 0% and working your way up, you start at 
100% and try not to work your way down.

To continue with my earlier example, this would change to the following:

There is a requirement to provide captions for multimedia content, if 
you don't you deduct 1%, if there is no ability to adjust the location 
of the captions, you deduct 2%.
