Expectation: convey the "false" value

Strength of this expectation for different types of assistive technologies:

  • Screen Readers: MUST
  • Voice Control: NA

  • The "false" value indicates that the input does not have an error.
  • Screen readers may imply this by not conveying the presence of the attribute at all. Most screen readers do not explicitly indicate that the input is valid.
