What does UBL-CR-676 mean? A UBL invoice should not include the PaymentMandate/ID schemeID

Why did my invoice fail UBL-CR-676?

The schemeID attribute on cac:PaymentMandate/cbc:ID (the direct debit mandate reference, BT-89) should not be used. EN 16931 defines the mandate reference as a plain identifier without a scheme, so the attribute falls outside the core model and triggers a warning. Send the mandate reference as element content only.
