A non-web document (one that is not a web page and neither embedded in nor rendered with one) must meet the document versions of WCAG 2.1 guideline 2.1 (keyboard accessible). SC 2.1.1 and 2.1.4 apply as written and no keyboard trap is restated for documents (Table 10.3); 2.1.3 is void.
This control maps to 1 controls across 1 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
The graph holds this control, the 1 it maps to, and the evidence behind each claim, over MCP and REST.
