What does UBL-CR-002 mean? A UBL invoice should not include the UBLVersionID or it should be 2.1

Why did my invoice fail UBL-CR-002?

The cbc:UBLVersionID element should either be absent or have the value 2.1. EN 16931 invoices are defined on UBL 2.1, so any other version claim is inconsistent with the syntax binding.
