The current development branch of Digester in the jakarta-commons project
has just such a feature -- there is a new rule type called
FactoryCreateRule, to which you pass an object that implements
ObjectCreationFactory. This works wonders, for example, when you need to
instantiate an object that does not have a zero-args constructor, or where
you *must* call an underlying factory method to create the thing, instead
of Class.newInstance().
