Document vocabulary and checks

German VAT invoice particulars in the structured component, eight-year VAT invoice retention, and the domestic-B2B structured e-invoice definition and transition boundary are reviewed from the current BMF FAQ. This generator does not create a validated structured e-invoice. Applicability, B2B status, cross-border treatment and exceptions remain transaction-specific checks.
