    # src/Acme/EventBundle/Resources/config/validation.yml
Acme\EventBundle\Entity\Participant:
    properties:

message

type: string default: This value should be {{ limit }} or less.

The message that will be shown if the underlying value is greater than the limit option.

invalidMessage

type: string default: This value should be a valid number.

The message that will be shown if the underlying value is not a number (per the is_numeric PHP function).
