Use the Workflow Parameter Definition (WFPD) form to set parameters for a WfMS
workflow definition. You can access this form directly, or by detailing from the Parameters
field on the Workflow Definition (WFDF) form.
Parameters that you set here, at the workflow definition level (versus on the individual
activities), become the default for all activities in the workflow definition. However, you can
override some of the parameters individually at the activity level.
