There are inconsistent requirements for SubjectName in an Application Instance Certificate in Part 6 and Part 12

Part 6
Table 49 – Application Instance Certificate
subject requires CN and O (CommonName and Organization)
The Common Name attribute shall be specified and should be the productName or a suitable equivalent. The Organization Name attribute shall be the name of the Organization that executes the application instance. This organization is usually not the vendor of the application

Part 12
7.9.4 StartNewKeyPairRequest
Requires O or DC
If the certificateType is a subtype of ApplicationCertificateType the Certificate subject shall have an organization (O=) or domain name (DC=) field. The public key length shall meet the length restrictions for the CertificateType. The domain name field specified in the subject is a logical domain used to qualify the subject that may or may not be the same as a domain or IP address in the subjectAltName field of the Certificate.

I am not even sure where the strange text for DC is coming from and what use case it should cover
