Clarification on System-Generated _repo.createDate and _repo.modifyDate Fields in XDM Individual Profile

[SiddarthK]

Hi,

I have a question regarding the _repo.createDate and _repo.modifyDate fields in the XDM Individual Profile schema. I understand that these fields are created by default, but I would like to confirm whether their values are automatically generated by the system when the schema is created or updated, or if these values must be explicitly populated during data ingestion.
