Technologies used in an unsupported or non-conforming way do not block access to the rest of the page; the page still meets the requirements when technologies not relied upon are on, off or unsupported; and criteria 1.4.2, 2.1.2, 2.3.1 and 2.2.2 apply to all content on the page, including content not relied upon.
This control maps to 3 controls across 2 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 3 it maps to, and the evidence behind each claim, over MCP and REST.
