WAI-ARIA: Role=Landmark

A perceivable section containing content that is relevant to a specific, author-specified purpose and sufficiently important that users will likely want to be able to navigate to the section easily and to have it listed in a summary of the page. Such a page summary could be generated dynamically by a user agent or assistive technology.

Authors designate the purpose of the content by assigning a role that is a subclass of the landmark role and, when needed, by providing a brief, descriptive label.

Elements with a role that is a subclass of the landmark role are known as landmark regions or navigational landmark regions. Assistive technologies SHOULD enable users to quickly navigate to landmark regions. Mainstream user agents MAY enable users to quickly navigate to landmark regions.

Note: landmark is an abstract role. Authors should not use this role in content.
