Hier ist ein JSON Schema, das international gültige Kontoinformationen erfasst. Es berücksichtigt Bankkontodaten wie IBAN, SWIFT/BIC, Kontonummer, Bankleitzahl und weitere Felder, die weltweit verwendet werden könnten.

In diesem JSON Schema ist es möglich, mehrere Einträge desselben Typs in einem Array zuzulassen, selbst wenn der Typ innerhalb einer oneOf-Definition steht. Die Verwendung von oneOf bedeutet jedoch, dass jeder einzelne Eintrag im Array entweder das Schema für eine natürliche Person oder für eine juristische Person erfüllen muss.
