What Are Optional Components of a Conformance Claim?
Section 5.3.2 of WCAG 2.1 lists additional information you can include in a conformance claim to help users, clients, and regulators better understand your accessibility status. These components are not required, but are recommended for greater transparency and clarity.
Recommended Optional Components
Consider including the following in your conformance claim:
- Success criteria beyond the claimed level that have been met (e.g., if you meet some AAA criteria but claim AA)
- Technologies used but not relied upon (features present but not required for accessibility)
- User agents and assistive technologies used for testing
- Specific accessibility characteristics of the content (such as ARIA usage, keyboard navigation, etc.)
- Any additional steps taken to enhance accessibility beyond WCAG requirements
- Machine-readable metadata for technologies relied upon and the conformance claim itself
- Contact information for accessibility feedback
- Date of last review or update
Why Include Optional Components?
- Transparency: Helps users understand the scope and limitations of your claim
- Clarity: Makes it easier for others to evaluate your accessibility status
- Continuous improvement: Encourages regular review and updates
- Legal and procurement: May be helpful for contracts or compliance
