Applicability
This rule applies to iframe elements that are included in the accessibility tree and that can be accessed by sequential focus navigation.
Note: frame element is deprecated, this rule does not consider frame or frameset elements.
Expectation
Each target element has an accessible name that is not empty ("").
Assumptions
If an iframe is not perceived by the user as a single control, it does not qualify as a user interface component under WCAG 2. In such a scenario, failing this rule would not fail success criterion 4.1.2. Unless the iframe is both removed from the accessibility tree and removed from sequential focus navigation, they usually are considered to be user interface components.
