So in your custom validator you can override doValidation()

        override protected function doValidation(value:Object):Array
        {
                var a:Array = super.doValidation(value);

                if (a.length > 0)
                        return a;
                
                var a1:Object = EmailValidator.validateEmail(this, 
value.emailInput, null);
                var a2:Object = EmailValidator.validateEmail(this, 
value.emailCInput, null);

                return a1.concat(a2);
        }
