I'm not native English speaker and I personally find confusing that sequence of characters "mandatory" is used as verb and also as name of the key. "optional mandatory" sounds like a joke.

To clarify this I propose to rename "mandatory" field to "critical", which terminologically aligns with X.509 and also LDAP.
