What it means
The check requires a schemeID attribute on ram:BuyerAgentTradeParty/ram:URIUniversalCommunication/ram:URIID. It checks only whether the attribute exists, not its value. FX-SCH-A-000669 separately checks non-empty scheme values against the accepted list.
Why it matters
The scheme identifies the type of electronic address alongside the address value.
How to fix it
Check the type of electronic address supplied for the buyer's agent. Add schemeID to its ram:URIID using the matching code from the Extended profile's electronic address scheme list, such as EM for an email address. Export the invoice again and recheck it.
