What it means
For each ram:EmailURIUniversalCommunication under ram:UltimateShipToTradeParty/ram:DefinedTradeContact in the header delivery section, this rule requires exactly one direct ram:URIID child. It counts elements, not whether the email address is filled in or valid.
Why it matters
The Extended profile gives each contact email block one address field. Omitting or repeating that field does not match the required structure.
How to fix it
Check the final delivery recipient's contact email. In ram:UltimateShipToTradeParty/ram:DefinedTradeContact/ram:EmailURIUniversalCommunication, keep exactly one ram:URIID containing the intended email address. If the email entry is not required for your invoice, remove its whole communication block instead. Export and recheck.
