What it means
This rule counts the direct ram:CompleteNumber children of each ram:FaxUniversalCommunication under ram:ShipFromTradeParty/ram:DefinedTradeContact. It requires one element, but does not check whether its text is empty or is a valid fax number.
Why it matters
The Extended profile requires one number field within each contact fax block. Omitting or repeating that field does not match the required XML structure.
How to fix it
Under ram:ShipFromTradeParty/ram:DefinedTradeContact/ram:FaxUniversalCommunication, add ram:CompleteNumber if it is missing or remove extra ram:CompleteNumber elements. Put the intended fax number in the remaining element, then export your invoice again and recheck it.
