type: string default: This value is not a valid datetime.
This message is shown if the underlying data is not a valid datetime.
type: mixed default: null
2.6 新版功能: The payload option was introduced in Symfony 2.6.
This option can be used to attach arbitrary domain-specific data to a constraint. The configured payload is not used by the Validator component, but its processing is completely up to.
For example, you may want to used several error levels to present failed constraint differently in the front-end depending on the severity of the error.
