Comment (by mattheu):

 I'm not sure whe want to go too far down the path of trying to validate
 aria attributes and should probably allow aria-* attributes on all
 elements. The bigger complexity is that certain aria attributes are only
 supported for certain `role` attributes.

 I have uploaded a few patches.

 The first adds unit tests for all the allowed aria attributes. It
 currently fails.

 The second patch - I looked into adding all the aria attributes to global
 attributes. This works OK, but the list of attributes is a long one, and
 we would have to maintain this if anything changes. It is useful if we
 want to go further with this.

 The third patch is a bit simpler and just whitelists any attributes that
 start with `aria-`.
