Any information or functionality that is provided
                  in a way that is not accessibility supported is also available in a way that is accessibility
                  supported. (See Understanding accessibility support .) 5.2.5 Non-Interference If technologies are used in a way that is not accessibility supported , or if they are used in a non-conforming way, then they do not block the ability
                  of users to access the rest of the page. In addition, the Web page as a whole continues to meet the conformance requirements under each of the following
                  conditions: when any technology that is not relied upon is turned on in a user agent, when any technology that is not relied upon is turned off in a user agent, and when any technology that is not relied upon is not supported by a user agent In addition, the following success criteria apply to all content on the page, including
                  content that is not otherwise relied upon to meet conformance, because failure to
                  meet them could interfere with any use of the page: 1.4.2 - Audio Control , 2.1.2 - No Keyboard Trap , 2.3.1 - Three Flashes or Below Threshold , and 2.2.2 - Pause, Stop, Hide . Note If a page cannot conform (for example, a conformance test page or an example page),
                  it cannot be included in the scope of conformance or in a conformance claim. For more information, including examples, see Understanding Conformance Requirements .
