  *  A high level component used to render a drop-down list of options that the user may select.
 24  
  *
 25  
  *  Informal parameters are applied to the <select> tag.  To have greater control over the 
 26  
  *  <option> tags, you must use a Select and Option or a concrete class 
 27  
  *  of {@link org.apache.tapestry.link.ILinkRenderer} with the {@link OptionRenderer}.
