Explanation

Code 30 is used to indicate that ARIA roles are use to organize the structure and identify landmarks for navigation.

This code is not used to identify that ARIA roles, states, and properties are used to make dynamic content accessible (see code 31).

For digital publications, DPUB-ARIA defines publishing-specific structures and landmarks.

Note that ARIA roles should only be used where the enhance the meaning or functionality of existing markup. It is better to use native HTML elements than use ARIA roles to give generic elements the meaning of more appropriate elements.

Only for use in ONIX 3.0 or later.

Examples
