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