Vault
The AccessUX Vault is a plain-English library of the W3C Web Content Accessibility Guidelines (WCAG) 2.2.
Plans. Everyone. The Vault is on the AccessUX website. You do not need a SiteScan plan to read it.
WCAG is the standard SiteScan checks against. The official text is precise, and it is hard to read in the middle of a fix. The Vault restates each requirement so you can see what it is asking for.
When a bug names a rule, open the Vault, start with the principle, then the guideline, then the success criterion. Come back to it whenever you need the requirement in clear language: while you write a My Bug, while you review a fix, or while you explain a result in the PDF.
The Vault explains the rule. Your SiteScan list shows where that rule failed on your pages. Use them together.
