If CSS is not used to toggle the visual representation of the check mark, the author could include additional markup and scripts to manage an image that represents whether or not the menuitemcheckbox is checked.

For example, the single-quote character can be encoded as "'" in HTML. The parts of a figure MAY be user-navigable. Indicates an element is being modified and that assistive technologies MAY want to wait until the modifications are complete before exposing them to the user. See the WAI-ARIA Authoring Practices for details on implementing a tab set design pattern. For any element with an explicit or inherited role of presentation and which is not focusable, user agents MUST ignore role-specific WAI-ARIA states and properties for that element. Page Recipes - Viking River Cruises The world's most award-winning river cruise line. There is no implicit role for "foo", so only the contents are exposed. Where to Book A River Cruise Now.

However, when a group is used in the context of a listbox, for example, authors MUST limit its children to option elements. When a state change occurs, the user agent provides the appropriate event notification to the accessibility API. The processing might not be identical because of lexical differences between the host language feature and the WAI-ARIA feature, but generally the user agent would expose the same information to the accessibility API. When defining the column span of cells or gridcells in a native table, authors SHOULD use the host language's attribute instead of aria-colspan.
