/**
 * Classes that implement this interface provide methods
 * that deal with the events that are generated when an
 * accessibility client sends a message to a control.
 * <p>
 * After creating an instance of a class that implements
 * this interface it can be added to a control using the
 * <code>addAccessibleControlListener</code> method and removed
 * using the <code>removeAccessibleControlListener</code> method.
 * When a client requests information the appropriate method
 * will be invoked.
 * </p><p>
 * Accessibility clients use child identifiers to specify
 * whether they want information about a control or one of its children.
 * Child identifiers are positive integers > 0.
 * The identifier CHILDID_SELF (0) represents the control.
 * </p><p>
 * Note: This interface is typically used by implementors of
 * a custom control to provide very detailed information about
 * the control instance to accessibility clients.
