    public interface Role

A generic ARIA Role. This interface defines generic methods for setting, getting, and removing attributes on DOM Elements so that they can be identified by screen readers. Subtypes define methods for specific roles.

The ARIA specification defines a hierarchy of roles, which is mirrored here as a hierarchy of Java interfaces. Some roles are abstract and define methods that are common to their children. Only concrete roles (available via methods in `Roles`) should be used to modify HTML elements.

For more details, see The Roles Model in the ARIA specification.
