type: String default: This value is not a valid ISSN.
The message shown if the given value is not a valid ISSN.
type: Boolean default: false
The validator will allow ISSN values to end with a lower case ‘x’ by default.
When switching this to true, the validator requires an upper case ‘X’.
type: Boolean default: false
The validator will allow non hyphenated ISSN values by default. When switching
this to true, the validator requires a hyphenated ISSN value.
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.
