简单的WSDL错误“部分”为其元素定义了无效值”。元素声明必须引用架构中定义的有效值”

Question

我正在尝试编写一个具有内联xsd的简单wsdl文件。但是我在wsdl文件中收到以下标记为“ *”的错误。我提到了另一个Stack Overflow问题，但是在这个问题上没有任何帮助。我刚刚编辑了xsd和wsdl文件，以在每个文件中包含名称空间以获取有关文件的更多详细信息。您可能需要注意，这是我在本地计算机上创建的文件。以下是我的代码。

        xsd file:


         <?xml version="1.0" encoding="UTF-8"?>
    <schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="http://www.example.org/bookService" xmlns:tns="http://www.example.org/bookService" elementFormDefault="qualified">
     <element name="BookServiceRequest"
     type="tns:BookServiceRequestType">
     </element>

     <complexType name="BookServiceRequestType">
     <sequence>
     <element name="limit" type="int"></element>
     </sequence>
     </complexType>

     <complexType name="BookServiceResponseType">
     <sequence>
     <element name="book" type="tns:BookType" maxOccurs="unbounded" minOccurs="0"></element>
     </sequence>
     </complexType>

     <element name="BookServiceResponse"
     type="tns:BookServiceResponseType">
     </element>

     <complexType name="BookType">
     <sequence>
     <element name="title" type="string" maxOccurs="1" minOccurs="1"></element>
     <element name="author" type="string" maxOccurs="1" minOccurs="1"></element>
