maximumLifetime property
Optional. The maximum lifetime allowed for issued Certificates that use this template. If the issuing CaPool's IssuancePolicy specifies a maximum_lifetime the minimum of the two durations will be the maximum lifetime for issued Certificates. Note that if the issuing CertificateAuthority expires before a Certificate's requested maximum_lifetime, the effective lifetime will be explicitly truncated to match it.
Implementation
final String maximumLifetime;
