Problem Description
An invoice shall carry a Specification identifier (BT-24) that names the syntax and business rules the document follows.
ERROR
XRechnung 3.0
Context and Significance
This is a core EN16931 rule; the identifier tells the validator which rule set to apply, so it must be present before any other check can run.
Solution
Add cbc:CustomizationID with the EN16931/XRechnung specification URN, for example urn:cen.eu:en16931:2017#compliant#urn:xoev-de:kosit:standard:xrechnung_3.0.
