BR-DE-17: Invoice type code (BT-3) must use a code this document type allows

ExampleXRechnung 3.0 (UBL)

An invoice built like a valid one, except for this:

<Invoice xmlns="urn:oasis:names:specification:ubl:schema:xsd:Invoice-2" xmlns:cac="urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2" xmlns:cbc="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2">
  <cbc:CustomizationID>urn:cen.eu:en16931:2017#compliant#urn:xoev-de:kosit:standard:xrechnung_3.0</cbc:CustomizationID>
  <cbc:ProfileID>urn:fdc:peppol.eu:2017:poacc:billing:01:1.0</cbc:ProfileID>
  <cbc:ID>INV-1001</cbc:ID>
  <cbc:IssueDate>2026-01-15</cbc:IssueDate>
  <cbc:InvoiceTypeCode>999</cbc:InvoiceTypeCode>
  <cbc:DocumentCurrencyCode>EUR</cbc:DocumentCurrencyCode>
  <cbc:BuyerReference>04011000-12345-67</cbc:BuyerReference>
</Invoice>

The validator says: Invoice type code (BT-3) carries 999, which is not a value this document type allows.

How to fix it

Replace the value in Invoice type code with one this document type allows.
