I think the 'testWRD.xpdl' provides a useful example how to deal with
custom datatypes. You can have a look at the implementations for the
classes in 'lib/engine/wrd.jar'.

public class Foo implements Serializable, Cloneable {

}

If i remember correctly you are advised *not* to put a lot of payload
into these dataypes and rather use pointers to external ressources(for
example files).
