  * The Select element lets users pick from a list of options. Each option is specified by an Option
 26   
  * element. Each Option element may have one line of formatted text (which may be wrapped or
 27   
  * truncated by the user agent if too long). Unless multiple selections are required it is generally
 28   
  * easier to use the {@link PropertySelection}component.
