This page provides an HTML view of the Rulesets XML file. It lists unique identifiers for the success criteria of specific versions of the Web Content Accessibility Guidelines 2.0. These identifiers are used by developers, in combination with the Test Case Description Language (TCDL) 2.0, to declare the specific version of the Guidelines for which test cases were developed.
