	 *  A flag that indicates whether child objects can receive focus
	 * 
	 *  <p>This is similar to the <code>tabChildren</code> property
     *  used by the Flash Player.
	 * 
	 *  <p>This is usually <code>false</code> because most components
     *  either receive focus themselves or delegate focus to a single
     *  internal sub-component and appear as if the component has
     *  received focus.  For example, a TextInput contains a focusable
     *  child RichEditableText control, but while the RichEditableText
     *  sub-component actually receives focus, it appears as if the
     *  TextInput has focus.  TextInput sets <code>hasFocusableChildren</code>
     *  to <code>false</code> because TextInput is considered the
     *  component that has focus.  Its internal structure is an
     *  abstraction.</p>
     *
	 *  <p>Usually only navigator components like TabNavigator and
     *  Accordion have this flag set to <code>true</code> because they
     *  receive focus on Tab but focus goes to components in the child
     *  containers on further Tabs.</p>
