What it means
The rule checks that rsm:ExchangedDocument has no direct ram:RevisionDateTime child. An empty element also triggers the warning.
Why it matters
The EN 16931 CII mapping does not use this document revision field. The warning does not establish whether a recipient will accept the invoice.
How to fix it
Remove the whole ram:RevisionDateTime element from rsm:ExchangedDocument, not just its value. If your invoicing software generates it, ask its support to omit it from the CII export. Check the updated file again.
