What it means
In the Extended profile of Factur-X and ZUGFeRD, each ram:EmailURIUniversalCommunication under ram:SalesAgentTradeParty/ram:DefinedTradeContact must contain exactly one ram:URIID. This test counts elements. It does not check whether their text is empty or has a valid email format.
Why it matters
The profile requires one address element within each contact email block. A missing or repeated element does not fit that structure.
How to fix it
Find the affected contact email block. Add a missing ram:URIID or remove repeated ram:URIID elements, keeping the intended email address. If you do not need this email entry, remove its whole ram:EmailURIUniversalCommunication block rather than only clearing the address text. Check the file again.
