ARIA attributes must conform to valid names

ARIA attributes starting with aria- must have valid names. Referring to a misspelled attribute or to one that does not exist will result in an invalid attribute and thus failure of this rule.

If the developer uses a non-existent or misspelled ARIA attribute, the attribute will not be able to perform the accessibility function intended by the developer.

In order to allow assistive technologies to convey appropriate information to persons with disabilities, user interface elements intended to improve the accessibility and interoperability of web and application content must conform to properly spelled and current ARIA attributes.

When developers do not use attributes defined in the WAI-ARIA 1.1 W3C Recommendation, they do not properly convey user interface behaviors and structural information to assistive technologies in document-level markup.
