This document forms a certificate profile for Qualified Certificates, based on RFC 2459, for use in the Internet. The term Qualified Certificate is used to describe a certificate with a certain qualified status within applicable governing law. Further, Qualified Certificates are issued exclusively to physical persons. The goal of this document is to define a general syntax independent of local legal requirements. The profile is however designed to allow further profiling in order to meet specific local needs. It is important to note that the profile does not define any legal requirements for Qualified Certificates.
