Re: definition of the a/aa/aaa levels

Thank you Steve for your feedback and interest.

First, allow me to note that there is plenty of room for disagreement.  But even if I rated several many things wrong, strong patterns are still apparent.

>  1. 1.2.*: CC, AD, and transcripts are nearly always invisible, no?

No, not to my thinking.  The early CC/AD controls were very invasive, so does inform my perspective.  But even with modern approach of overlaying them onto the video and having them disappear, it is a visual imposition on the designer.  Agreed, it is something we tend to take for granted nowadays, especially since the volume and timelines are going to be there anyway.  (I choose to believe that volume et al. rode the coattails of the CC button…)

Having the AD version available is not invisible, as it is either extra audio, or an alternative version, or one needs the AD on an extra channel.

Transcripts are not invisible either, as they need to be available and linked up on the Web page.

> 2. 1.3.1: Yes, this can be a big and complex criterion, but in most cases it's not hard to meet the essential pieces and nearly all of the techniques are invisible.

I agree with you about 1.3.1 being mostly invisible, so I changed that just now.  I agree in most cases that meeting 1.3.1 is easy, but any multilevel table is not, and those are pretty common.

> 3. 2.4.1: I would certainly disagree with being able to programmatically bypass repeated blocks of content as not being essential for navigation, and again this is nearly always invisible.

It being easy to ignore repeated blocks of content is not essential, not per the WCAG 2.0 definition, and not like alternative text nor captions nor keyboard access are essential.

Yes, some techniques for 2.4.1 are invisible, but I disagree about “nearly always”.  Skip Nav links are not invisible.  Using Headers to organize content has a visible impact.
