XML. XSD недопустимый элемент

Привет, у меня есть xml, который я пытаюсь использовать со схемой, которую я создал, но когда я пытаюсь разобрать xml, я получаю сообщение об ошибке ниже:

The element 'PartnerPSTNTransfer' in namespace 'http://localhost/Orders-PartnerPSTNTransfer-v1-0' has invalid child element 'InstallationAddress' in namespace 'http://localhost/Orders-PartnerPSTNTransfer-v1-0'. List of possible elements expected: 'Configuration' in namespace 'http://localhost/Orders-PartnerPSTNTransfer-v1-0'.

Ниже приведен мой XML, который я создал, и связанные с ним схемы:

У меня есть элемент InstallationAddress, объявленный в нужном месте перед элементом конфигурации, поэтому я смущен тем, почему он выбрал эту ошибку.
