WCAG 2.2 Criterion Mapping

Complete tracking of all WCAG 2.2 Level A and AA success criteria. Criteria with document-specific rules list the rule IDs. Criteria requiring human judgment show "Manual review". Criteria that apply only to web/app contexts show a dash. See the wcag-guide agent for full explanations of each criterion.

Note: WCAG 2.2 removed 4.1.1 Parsing (it is "always satisfied" in modern user agents and no longer tested).
