Mechanism: A mechanism is available to assist the user in completing the cognitive function test. Understanding 3.3.9 Show Hide techniques and failures for 3.3.9 Sufficient Advisory Failures Sufficient Techniques for Success Criterion 3.3.9 Note: Other techniques may also be sufficient if they meet the success criterion.
