Check that the Common Name attribute is specified for certificates.
Update SOPC_PKIProvider_CheckLeafCertificate
to verify that certificate Common Name is specified.
As specified in part 6 table 43 (v1.05.01) for X509 subject:
The Common Name attribute shall be specified and should be the productName or a suitable equivalent.
Since a "suitable equivalent" is not verifiable, we only check that this attribute is specified.
