the jpdl processdefinition can be extended by custom elements. You can e.g. add an attribute 'estimatedManHours' to a task element and retrieve the processdefinition runtime and get this parameter. You currently have to turn of validation on the server side for this as the processdefinitionparser is not namespace aware (yet I hope, as does Koen and Tom but not Gavin).
