BR-DE-22

The rule sets below word this rule differently; each wording is shown with its rule set.

error: the document is invalid

Why it fails

  • Two attachments (cac:AdditionalDocumentReference/cac:Attachment/cbc:EmbeddedDocumentBinaryObject) have the same filename, often attachment.pdf from a generator that names every file alike.

How to fix it

Give each embedded file a name of its own, such as timesheet-2026-09.pdf and delivery-note-4711.pdf.

What the rule checks

As the rule set's publisher wrote it. The rule runs on every element the context matches, and fails where the test is false; the validator reports the line of that element.
