PEPPOL-EN16931-R008

Explanation

PEPPOL forbids empty elements — an element must either carry a value or be omitted. Empty elements indicate a defect in the sender's invoicing software.

How to fix

Remove empty elements from the XML. (Typically a software-side issue, not user input — raise this with your invoicing software vendor; if you're receiving the invoice, ask the sender to address it with theirs.)
