The parties are not required. You only need to provide those parameters when adding extra parties to the document. Party parameters have the form of parameter_n. The letter “n” has to be replaced by a party index (starting with 0). Example:
- You must start with 0, or no extra parties will be added.
- If you skip a number, e.g., 0, 1, 3, 4, only parties 0 and 1 will be taken into consideration.
