Describing Semantics and Behavior
Provide an inter-operable way to describe the features of custom widgets:
- Role: Describes the type of widget, which implies the keyboard interaction.
- Properties and States: Describing features like "expandable", "checked" or "selected".
- Language independence: Roles, properties and states can be translated by the operating systems and assistive technologies to local languages.
- Labeling: Giving a widget and its components names to understand their purpose.
- Relationships: How different components relate to each other (e.g. descriptions, controls, owns).
- Grouping: Groups of related components (e.g. lists, menus, trees, tab panels).
