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