/**
* This enum describes the attributes that an assistive technology
* such as a screen reader can request from the scene graph.
*
* The {@link AccessibleRole} dictates the set of attributes that
* the screen reader will request for a particular control. For
* example, a slider is expected to return a double that represents
* the current value.
*
* Attributes may have any number of parameters, depending on the particular attribute.
*
* When the value of an attribute is changed by a node, it must notify the assistive technology
* using {@link Node#notifyAccessibleAttributeChanged(AccessibleAttribute)}. This will allow
* the screen reader to inform the user that a value has changed. The most common form of
* notification is focus change.
