/**
 * This is the <code>BeanInfo</code> descriptor for the
 * <code>org.apache.strutsel.taglib.html.ELFileTag</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.
