* expression.
*
* Because Spring's s:options tag takes a JSP EL expression, not a 'Spring beans aware'
* expression, this annotation is best used in conjunction with
* InternalResourceViewResolver.setExposeContextBeansAsAttributes (available in Spring
* 2.5+). You may also need to set springJspExpressionSupport to true in
* your web.xml.
