The XML snippets below would pass this check.

<Transaction>
    <Id>Debtor1Creditor1</Id>
    <Amount>1</Amount>
    <Debtor>
      <Name>Debtor1</Name>

    </Creditor>
</Transaction>

The other snippet below however would not pass this check.

<Transaction>

    <Amount>1</Amount>
    <Debtor>
      <Name>Debtor2</Name>
    </Debtor>
