 /**
 23  
  * This component serves as a container for one item that is listed as a choice
 24  
  * in a {@link Select}. A {@link Select}offers a selection of choices from
 25  
  * which usersu may choose one or more items. The select list is created using a
 26  
  * select element which contains a collection of option elements. A string or
 27  
  * text describing the item appears between the opening and closing option tags.
 28  
  * In order to have a dynamic onpick attribute it is better to use a concrete
 29  
  * class of {@link org.apache.tapestry.link.ILinkRenderer}with the
 30  
  * {@link OptionRenderer}.
