The ARIA value is used to indicate that ARIA roles are used to organize and improve the structural navigation of the publication (e.g., to identify key sections of the content and the purpose of hyperlinks).

This value is used when Document Structure, Landmark, Live Region, and Window roles are included.

It is not intended for use when ARIA roles, states and properties are used to make custom controls accessible. The accessibility of custom controls is covered by the accessibilityControl property.
