I suggest leaving them to WCAG, to avoid repetition and potential
conflict (should WCAG in some incompatible way).

"Sections should be introduced with the HTML heading elements (H1-H6).
Other markup may complement these elements to improve presentation
(e.g., the HR element to create a horizontal dividing line), but
visual presentation is not sufficient to identify document sections."

There are generic WCAG criteria (use markup properly) but nothing
specific to address this. "Use markup properly" implies that HTML5
need to define "proper" I guess, so we keep this? But every element
has a defined purpose, does that necessitate a need to turn each into
conformance criteria? (It might??) Maybe we are just identifying
common mistakes (i.e. where authors need guidance)... I'd like to see
them bundled into WCAG though. Probably just as extra techniques for
the relevant guidelines.

as with cite, this is the definition of ins.

HTML5 gives us the rules and algorithms - how this works. WCAG
provides conformance definitions:

And all of these were documented back in WCAG 1.0

I don't understand why we don't just leave it in WCAG ~:)
I'm sure there's a reason, I just don't know it.

cheers
