Merchant validation is the process by which a payment handler validates the identity of a merchant against some value (usually some cryptographic challenge response). Validated merchants are allowed to interface with a payment handler. The PaymentRequest's onmerchantvalidation event is invoked when the user agent requests merchant validation on behalf of a selected payment handler.
