    30   * This is the <code>BeanInfo</code> descriptor for the
    31   * <code>org.apache.strutsel.taglib.html.ELJavascriptValidatorTag</code>
    32   * class. It is needed to override the default mapping of custom tag attribute
    33   * names to class attribute names. <p> This is because the value of the
    34   * unevaluated EL expression has to be kept separately from the evaluated
    35   * value, which is stored in the base class. This is related to the fact that
    36   * the JSP compiler can choose to reuse different tag instances if they
    37   * received the same original attribute values, and the JSP compiler can
    38   * choose to not re-call the setter methods, because it can assume the same
    39   * values are already set.
