Structured remittance info invalid when validated against the XSD

[xuannghia]

Hello,
I am using this library to generate a file in the pain.001.001.09 format, and I’ve noticed that the file is invalid when validated against the XSD schema.
I only changed the remittanceInfo from the default test value to structuredRemittanceInfo.
Could you please help to check it?

    test.each([
      'pain.001.001.02',
      'pain.001.001.03',
      'pain.001.001.08',
      'pain.001.001.09',
    ])('%p schema matches', (format) => {
      var doc = new SEPA.Document(format);
      doc.grpHdr.id = 'XMPL.20140201.TR0';
      doc.grpHdr.created = new Date();
      doc.grpHdr.initiatorName = 'Example LLC';

      var info = doc.createPaymentInfo();
      info.requestedExecutionDate = new Date();
      info.debtorIBAN = 'DE87123456781234567890';
      info.debtorBIC = 'CUSTDEM0XXX';
      info.debtorName = 'Example LLC';
      doc.addPaymentInfo(info);

      var tx = info.createTransaction();
      tx.creditorName = 'Example Customer';
      tx.creditorIBAN = 'DE40987654329876543210';
      tx.creditorBIC = 'CUSTDEM0XXX';
      tx.amount = 50.23;
   
      tx.structuredRemittanceInfo = {
        type: 'SCOR',
        issuer: 'ISO',
        reference: '500234326411'
      };

      tx.end2endId = 'XMPL.CUST487.INVOICE.54';
      info.addTransaction(tx);

      const validation = validateSchema(doc.toString(), fs.readFileSync('schema/' + format + '.xsd'));
      expect(validation).toBe(true);
    });
  });
