ARIA attributes must conform to valid values

ARIA attributes starting with aria- must contain valid values. These values must be spelled correctly and correspond to values that make sense for a particular attribute in order to perform the intended accessibility function.

ARIA attributes (i.e. starting with aria-) must contain valid values. These values must be spelled correctly and correspond to values that make sense for a particular attribute to perform the intended accessibility function.

Many ARIA attributes accept a specific set of values. Allowed values, acceptable "undefined" values, and acceptable "default" values are required. Failure to comply with allowed values results in content that is not accessible to assistive technology users.
