One use case for this is to model validity ranges for discounts. These discounts can have an end date, or you can specify the time range for which they are valid. The approach can vary depending on country requirements and other factors.

Payment Terms Group (`Invoice/PaymentTerms`)	0..n	Groups information about the terms of payment.
Payment Terms (`Invoice/PaymentTerms/Note`)	0..1	A textual description of the payment terms that apply to the amount due for payment (Including description of possible penalties).
Percentage Discount (`Invoice/PaymentTerms/SettlementDiscountPercent`)	0..1	The discount as a percentage.
Terms Amount (`Invoice/PaymentTerms/Amount`)	0..1	The base amount for the discount.
Settlement Period End Date (`Invoice/PaymentTerms/SettlementPeriod/EndDate`)	0..1	Specify the end date, if you are using one.
Terms Installment Due Date (`Invoice/PaymentTerms/SettlementPeriod/InstallmentDueDate`)	0..1	The date any instalment is due.
Settlement Period Duration (`Invoice/PaymentTerms/SettlementPeriod/DurationMeasure`)	0..1	The length of the period for which the discount is valid.
Settlement Period Duration - Unit of Measure (`Invoice/PaymentTerms/SettlementPeriod/DurationMeasure [@unitCode='D']`)	0..1	Use this attribute to specify the units of the period, for example, use `D` for days.
