HTML-AAM contains a number of passively and/or informatively phrased RFC-2119 requirements.

These are just a few examples... There are more...

Is this an Author or User Agent requirement?

Where an HTML element or attribute has default WAI-ARIA semantics, it MUST be exposed to the platform accessibility APIs in a way that conforms to General rules for exposing WAI-ARIA semantics in the Core Accessibility API Mappings 1.2.

Does 'for instance' mean this is informative, not normative?

For instance, the video element MAY be exposed with a computedrole of html-video."

Needs to clarify that this is a User Agent requirement:

If a summary element is not a child of a details element, or it is not the first summary element of a parent details, then the summary element MUST be exposed with a generic role."

Spotted these when I gave the same feedback on the PDF-AAM draft... some of those were copied from here.
