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