What it means
In the Extended profiles of Factur-X and ZUGFeRD, each ram:FaxUniversalCommunication under ram:SellerTaxRepresentativeTradeParty/ram:DefinedTradeContact must contain exactly one ram:CompleteNumber child. This rule counts elements; it does not check whether their text is present or is a correctly formatted fax number.
Why it matters
The contact fax block has one field for the complete fax number. A missing or repeated number element does not meet the profile's structure.
How to fix it
Check the contact fax number for your seller's tax representative. In ram:SellerTaxRepresentativeTradeParty/ram:DefinedTradeContact/ram:FaxUniversalCommunication, add the missing ram:CompleteNumber or remove duplicates, keeping the intended fax number in one element. If you do not need the fax details, remove the whole fax block rather than leaving it without ram:CompleteNumber. Recheck the corrected file.
