Server uses of which TLS is going to be the biggest use case is the main
objective at present, most server certificates in the X.509 world have a
lot more than just dnsName, such as company name, maybe a contact, the
country, state/territory/province, town/suburb and so on and so forth.
This data is not mechanically processed (at least not in a way which is
consistent across implementations), so you can put it into notation data
subpackets.
