Checks for valid values in ARIA attributes

## Solution

Ensure ARIA attribute values match the expected type. Boolean attributes should be 'true' or 'false'. Enumerated attributes like aria-current have specific allowed values. Numeric attributes like aria-level must be numbers. Check the WAI-ARIA specification for valid values.
