 /**
 28   
 * WOString renders a dynamically generated string in the output.
 29   
 * Bindings are:
 30   
 * <ul>
 31   
 * <li>value: a property returning a value which will be rendered as the
 32   
 * output.  If a formatter is not used, then the value must be convertable
 33   
 * to a String with toString().</li>
 34   
 * <li>escapeHTML: a property returning a value convertable to a Boolean
 35   
 * indicating whether the any html characters in the output should be
 36   
 * escaped so they are shown as html characters rather than interpreted
 37   
 * as html.</li>
 38   
 * <li>formatter: a property returning a Format object that will be
 39   
 * used to format the value into a String.</li>
 40   
 * <li>dateformat: a property returning a DateFormat object that will be
 41   
 * used to format the value into a String.</li>
 42   
 * <li>numberformat: a property returning a NumberFormat object that will be
 43   
 * used to format the value into a String.  Not yet implemented.</li>
 44   
 * <li>valueWhenEmpty: a property returning a String that will be used
 45   
 * in place of an empty or null value.  Not yet implemented.</li>
 46   
 * </ul>
