About Equal Access Accessibility Checker Results
ACT rule results were generated using the latest `accessibility-checker` from NPM using the [ACT test driver](https://github.com/IBMa/equal-access/tree/master/accessibility-checker/test-act). Results were created using the `preview` archive and the `IBM_Accessibility` policy. Mappings from ACT Rules to Accessibility Checker rule ids and reason codes can be found in [`act_aligned.json`](https://github.com/IBMa/equal-access/blob/master/accessibility-checker/test-act/act_aligned.json) and [`ace_mapping.js`](https://github.com/IBMa/equal-access/blob/master/accessibility-checker/test-act/ace_mapping.js). Results indicate the rule ids and reason codes related to the ACT rule are generated in the following format: `RuleId1:ReasonCode1,ReasonCode2|RuleId2:ReasonCode3,ReasonCode4`.
Results in this page are taken from a public test report published by IBM Accessibility. Data is published using the EARL+JSON-LD data format.
