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