*  <li> <code>'Win2'</code> (of type <code>XWindow</code>):

*  <li> <code>'CONTROL'</code> (of type <code>XControl</code> and
*   must implement <code>XTextComponent</code> interface):

*  <li> <code>'XChangeBroadcaster.Changer'</code>

*   <code>XTextComponent</code> is not supported by the tested
