New Profile review

Following the most recent review of the PKI-related Approval Profiles it was decided that a new Profile single was needed to cover a service providing the functionality of a Root Certificate Authority rather than, as currently, require such a service to use the Certification Authority Profile (tSd0102) and the associated 5 or 6 sub-service Profiles.

To participate in a review of the result of that process, please visit the review page.
