WCAG 1.3.1 said - and says - that anything that is visually presented (obvious to someone with vision) needs to be programmatically determinable or be presented in text. If something looks like a Header - it must be marked up as a header. If it is navigation, it needs to be possible for someone without vision to tell that it is navigation. Etc. Usually it is obvious from the contents that they are nav or footer. But if it is not - then something needs to be provided. Always have. but be careful with failures. We often found that the failure — after we stopped specifying things needed to be done a particular way - ended up just being a parrot of the SC which doesn’t help. I think failures are the hardest thing to do right — and are the most dangerous when done wrong. RE old and new sites. If you passed things that should have failed — that doesnt mean you need to pass them now. But I would be careful to not fail things that really arent a problem. That is, it is easy to tell what they are without any special markup.

It was an information and relationship that was visual but not perceivable to blind people except by exploring around and guessing. Soon after, Landmarks came out and solved the problem. They took minutes to add to entire sites in most cases and allowed the blind user to know when they entered that section or not and also allowed them to easily jump to that region 2.4.1 > > The issue was brought up by Paul Adam who felt there should be a failure.
