Which principle is associated with the Success Criterion "name, role, value"?

The principle associated with the Success Criterion "name, role, value" is Robust. This criterion falls under the Web Content Accessibility Guidelines (WCAG), specifically ensuring that user interface components such as form inputs, buttons, and other interactive elements are properly identified programmatically.

When elements have their name (what they are called), role (what they do), and value (their current state or settings) defined, it allows assistive technologies, like screen readers, to convey this information accurately to users with disabilities. This emphasis on programmatic identification supports robust web content that remains compatible with current and future user agents, including assistive technologies and other tools.

The other principles—Perceivable, Operable, and Understandable—focus on different aspects of accessibility. For instance, Perceivable ensures that users can perceive the information presented, Operable ensures that all users can interact with the interface, and Understandable ensures that information and operation of the user interface are clear and consistent. Each principle plays a critical role in accessibility, but "name, role, value" specifically reinforces the robustness of web content enabling effective interaction across diverse technologies.
