Create a file named VacationRequest.xsd with the following syntax. This file includes the schema for the vacation request and subsequent response.

<schema attributeFormDefault="qualified" elementFormDefault="qualified"
        targetNamespace="http://xmlns.oracle.com/VacationRequest"
        xmlns="http://www.w3.org/2001/XMLSchema">
