When using references in schemas used to validate array items:

• array().items()
• array().ordered()

The references no longer point to the object containing the array itself. Instead, they point to the individual array item being validated. This means that a previous reference of Joi.ref('peer') must now be expressed as Joi.ref('...peer'). This is because:

• x and .x are now properties of the array item being validated
• ..x is a property of full array being validated
• ...x is a property of the object containing the array
