 A standalone validator is a class extending [[yii\validators\Validator]] or its child class. You may implement
 its validation logic by overriding the [[yii\validators\Validator::validateAttribute()]] method. If an attribute
 fails the validation, call [[yii\base\Model::addError()]] to save the error message in the model, like you do
-with [inline validators](#inline-validators). For example you will need to create the above validator into [[components/valdators/CountryValidator]],

 instead of `validateAttribute()` and `validate()` because by default the latter two methods are implemented
 by calling `validateValue()`.
