The properties node can hold properties for the steps in the process model.
It can also hold global properties, in a section with a reference of "global". These global properties are applied as a default to all steps. In the example below, companyName is defaulted to "ACME Limited" in all steps, except for the groupNotification step that defaults companyName to "ACME Group plc".
{ "global": { "companyName": "ACME Limited" }, "groupNotification": { "companyName": "ACME Group plc" } }
