 /**
 24  
 * WOConditional renders whatever is inside its opening and closing tags
 25  
  * only if a condition is met.
 26  
  * Bindings are:
 27  
  * <ul>
 28  
  * <li>condition: a boolean property that indicates whether the contents of the element
 29  
  * should be displayed, invoked, or passed the request form values.</li>
 30  
  * <li>negate: if this is true, then the behavior of the element is reversed, showing its
 31  
  * contents only if the condition is NOT met.</li>
 32  
  * </ul>
