Make sure Ace doesn't report DPUB ARIA roles as violations

[rdeltour]

aXe currently reports DPUB ARIA roles as critical violations (in its aria-roles rule). Ace shouldn't report these as violations.

Possible solutions:

• override the aria-roles rule with a custom implementation
• submit a PR to aXe to support DPUB ARIA roles

Yeah, that would be very useful.

I’ve just tested a complex epub with lots of footnotes, bib ref, etc., and literally wailed in fear and begged to be forgiven when checking the results.

Then I noticed that, 2742 of 2743 violations were about DPUB aria-roles but it was kinda tricky to check the results (I had to parse that first to eliminate those violations).

oh, sorry about the cold sweat 😖!

Nah don’t worry. Of all the files I could test, I picked the edge case. ;-)

I have just tested an ePub with ACE Beta version myself.
And I confirm. All DPUB ARIA roles are reported as critical errors, Which is quite ironic as I added these roles on purpose in order to systematically provide ARIA equivalents to epub:type attribute.
