Minimal payload

Every child of FarPay is optional, so the smallest valid payload is an empty FarPay element wrapped in its envelope.

<ExtensibleContent>
  <FarPay/>
</ExtensibleContent>

In practice a minimal-but-useful payload carries just a customer reference and a due date.

<ExtensibleContent>
  <FarPay>
    <CustomerNumber>ABCDE0123456</CustomerNumber>
    <PaymentDueDate>2026-12-31</PaymentDueDate>
  </FarPay>
</ExtensibleContent>

Because the readers match children by local name (xs:all), element order inside FarPay never matters.
