Errors: Issues which have been automatically determined as failures to meet success criteria in the Web Content Accessibility Guidelines (WCAG).
Warnings: Issues which have been automatically determined as failures to meet best practices in the Web Content Accessibility Guidelines (WCAG).
Reviews: Potential failures to meet best practices or success criteria in the Web Content Accessibility Guidelines (WCAG), which can only be confirmed by a manual inspection.
