The current HTML 5 draft doesn't mention ARIA anywhere. Perhaps it

Unfortunately a brief mention is insufficient as aria functionality
overlaps substantially with HTML functionality and so processing
requirements for aria-in-html need to be carefully considered (so we can
answer questions like "how does <div aria-role='heading'> affect the
outline algorithm"). This has not yet happened.
Okay, so I can speak to this. I developed first browser implementation
of ARIA -- the one in Firefox.
ARIA doesn't really overlap with HTML, because ARIA only reports what a
JS developer is using elements for.
So ARIA semantics should not affect behavior. Any code for dealing with
ARIA markup should be strictly in the accessibility API support code
(MSAA/IAccessible2/ATK/AT-SPI/UI Automation/Universal Access).
A div need not affect the outline algorithm, etc. any more than a div does.
Thus it should not be complicated to mention ARIA in the spec.
