Expectation: convey the presence and value of the aria-level attribute
Rationale:
The user needs to know that the element has a level and the value of that level.
Strength of this expectation for different types of assistive technologies:
- Screen Readers: MUST
- Voice Control: NA
Examples:
- When applied to a heading, the heading might be announced as something like "<name> heading level <level>"
