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"
}
}
