Unit code list agency name attribute should not be present
'Unit code list agency name attribute' is present, but this profile does not allow it — nothing in the EN 16931 semantic model maps to it.
Remove 'Unit code list agency name attribute'. It is almost always left over from a generic template or a library that emits every field of the underlying schema. Reported as a warning.
