What it means
Checks that rsm:ExchangedDocument has no direct ram:CopyIndicator child. Both true and false values trigger the warning because the rule checks the element's presence.
Why it matters
The EN 16931 CII mapping does not use this indicator. Its presence alone does not mean the document is marked as a copy, because the value can be false.
How to fix it
Remove ram:CopyIndicator from rsm:ExchangedDocument. Changing its value to false does not satisfy this rule. If your software adds the element, ask your software supplier to omit it from the CII export, then recheck the file.
