BR-DE-2
XRechnung requires a named contact for the seller, and the group is missing.
Why it happens
German public-sector receivers require a human contact point on the invoice. Optional under EN 16931, mandatory here.
How to fix it
Add cac:AccountingSupplierParty/cac:Party/cac:Contact (UBL) or ram:SellerTradeParty/ram:DefinedTradeContact (CII), and populate all three of BT-41 name, BT-42 telephone and BT-43 email — see BR-DE-5, BR-DE-6 and BR-DE-7.
The official rule
