The <set-property> tag is a general way to set JavaBeans properties on an
underlying implementation class, even though the property name is not
defined as a valid element in the DTD.

This logic assumes that the SuccessAction class has public setter methods
setPrimaryWorkflow(), setNewState(), and setNextState() -- you can still
configure them in struts-config.xml even though these property names are
not allowed on the <action> element itself.
Many of the Struts elements allow <set-property> tags to be nested inside
-- check out the Struts DTD for more information.
