Add rule BR-DE-26 to UBL CreditNote

The rule BR-DE-26 is currently only implemented for UBL Invoice and CII, but missing in UBL CreditNote. Since the document type code 384 is called "Corrected Invoice", but there is no type "Corrected CreditNote" in the list https://unece.org/fileadmin/DAM/trade/untdid/d16b/tred/tred1001.htm - I would recommend to add the rule "BR-DE-26" also to UBL Credit Note, to allow the possibility for "Corrected CreditNotes".

@renzo.kottmann @barbara.dewein @lars.roelker-denker @philip.helger I've added BR-DE-26 to CreditNote, but I'm not sure, whether it is correct to use another document type code in credit note than 381. In this example I have to use 384.

I think 384 (Corrected Invoice) is just fine. Exactly because there is not code for "Corrected CreditNote", using "Corrected Invoice" can be considered a viable workaround

This may need to be reevaluated in the context of CIUS conformity
