Module invoice 

Semantic invoice: parties, lines, totals, and Table 2 groups.

Structs

AllowanceCharge

BG-20 / BG-21 document level allowance or charge.

Contact

BG-6 / BG-9 contact.

Delivery

BG-13 delivery information.

DocumentTotals

BG-22 document totals. Absent optional amounts are None, not 0.00.

Invoice

Semantic invoice. Fields are pub on 2.x so embedders can Invoice::blank then set terms. Do not match on the struct layout — #[non_exhaustive] would be a 3.0 break. A proved document is crate::Validated.

BT-21 / BT-22 invoice note.

ItemAttribute

BG-32 item attribute: BT-160 name + BT-161 value (AdditionalItemProperty).

Line

LineAllowanceCharge

Line allowance/charge (BG-27/28). No tax child: Peppol/PINT inherit the line category. Line A/C already sits in BT-131. Do not add them again in taxable_for.
