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