 /**
 23  
  * The do element provides a general mechanism for the user to act upon the
 24  
  * current card, in other words a card-level user interface element. The
 25  
  * representation of the do element is user agent dependent and the author must
 26  
  * only assume that the element is mapped to a unique user interface widget that
 27  
  * the user can activate. For example, the widget mapping may be to a
 28  
  * graphically rendered button, a soft or function key, a voice-activated
 29  
  * command sequence, or any other interface that has a simple "activate"
 30  
  * operation with no inter-operation persistent state. The do element may appear
 31  
  * at both the card and deck-level.
