RE: Call for Review: ACT Rules Format 1.0 Final Working Draft

Section "13. Accessibility Support":

"Because of this, ACT Rules are not necessarily applicable in all test scenarios. For instance, a web page that has to work in assistive technologies that have no WAI-ARIA [WAI-ARIA]<https://www.w3.org/TR/act-rules-format/#biblio-wai-aria> support, wouldn't be tested with an ACT Rule that relies on WAI-ARIA support, since this could lead to false positive results."

This is not understandable without further examples or rewording especially what "false positive results" would mean.

Concealment does not improve things.
I mean, shouldn't the rule set actively *encourage* the USE of WAI-ARIA instead of doing protectionism for older AT and user agents?
Of course, respective rule messaging should be flagged accordingly.
