I'm afraid I've got to disagree with most of that, Birkir,

You are misunderstanding what 1.3.1 says. It does not say anything about what the heading structure should be. It says that if something visually looks like a heading, it should be marked up as a heading. Visual relationships and information must be conveyed programmatically. The starting point for this is what the content looks like, and you must be able to determine the author's intent. If you can't see it, you can't do that in many cases. I agree that if you can perceive a data table, then you can tell if it is marked up correctly. But if tabular content is marked-up using div or span elements, you may not be able to tell that it should be a table.

1.3.2 is not about a logical content order. It is about identifying the correct content order, which may not be the same. The programmatic content order may well seem logical, yet be incorrect.

I don't want to appear to be the bad guy picking on blind people, but whenever this topic comes up I find that people ignore all the stuff they can't do. It may well be that this is because they simply cannot perceive all those things, so the task of testing appears simpler than it actually is. Depending on what you are testing, it can be extremely difficult even if you are fully able.
