A UBL invoice should not include the InvoiceLine DespatchLineReference

This is the rejection, word for word: „[UBL-CR-529] Your invoice contains an InvoiceLine DespatchLineReference element which is not allowed in EN16931 invoices. This element must be removed.

What to have readyNothing. The file has to be re-exported from your invoicing software; we check it again afterwards.
What we doInvoice Navigator automatically removes the disallowed `cac:DespatchLineReference` element from your Invoice.
If you enter it yourself in your invoicing software
Before
<Invoice>
  <cac:DespatchLineReference>value</cac:DespatchLineReference>
</Invoice>
After
<Invoice>
  <!-- cac:DespatchLineReference removed for EN 16931 compliance -->
</Invoice>

Element order is part of the rule: if the element sits in the wrong place, the validator rejects with UBL-CR-529.
