What it means
Each ram:EmailURIUniversalCommunication under ram:BuyerAgentTradeParty/ram:DefinedTradeContact must contain exactly one direct ram:URIID child. This test counts elements; it does not check whether the address is empty or has a valid email format.
Why it matters
The Extended profile requires a single address element within each contact email block.
How to fix it
Find the affected ram:EmailURIUniversalCommunication in the buyer agent's contact details. Put the contact's email address in one ram:URIID and remove any additional ram:URIID elements from that block. Re-export and recheck your invoice.
