Need to add ARIA landmarks

[becka11y]

I just realized that there are not proper landmarks in the viewer. The toolbar is marked as a navigation landmark but there is no role=main. I think we also need a landmark on the next/prev button area.

I am working out the details of what the landmarks should be and will implement.

This is a V1 a11y issue.

To clarify, this is NOT the EPUB landmarks though it seems there is some overlap in intent. Is that correct?

Correct, this is NOT about EPUB landmarks. These landmarks will allow the (screen reader) user to find the sections of the reader page - toolbar, epub content area, and page navigation area.

Although I do need to think about possible overlap with landmarks defined within the epub content. The ARIA spec states that where SHOULD (but not MUST) only be one instance of certain landmarks such as banner and main. If an EPUB includes landmarks they could overlap with what the cloud reader defines. However, the epub landmarks will be within the cloud reader's "main" section.

The Accessible EPUB 3 book does contain at least the complementary info landmark and it all works fine with the reader landmarks defined.

I'm just not sure if the page arrows should be marked as a landmark region or not and am asking around.
