如何在XSD中声明多个组？

Question

在我的情况我XSD应该有一个根标签， ＃XSD＃

<xs:group name="location"> 
    <xs:sequence> 
    <xs:element name="city" type="xs:string"/> 
    <xs:element name="flat_num" type="xs:string"/> 
    <xs:element name="landmark" type="xs:string"/> 
    <xs:element name="street" type="xs:string"/> 
    </xs:sequence> 
</xs:group> 

<xs:group name="student"> 
    <xs:sequence> 
    <xs:element name="firstname" type="xs:string"/> 
    <xs:element name="lastname" type="xs:string"/> 
    <xs:element name="mothername" type="xs:string"/> 
    <xs:element name="fathername" type="xs:string"/> 
    </xs:sequence> 
</xs:group> 

<xs:element name="Student_details" type="details"/> 

<xs:complexType name="details"> 
    <xs:group ref="location"/> 
    <xs:group ref="student"/> 
</xs:complexType> 
</xs:schema> 

当我使用XML验证，它说这种格式是错误的， 任何一个可以帮助在多个组让我知道如何创建多个组

你缺少复杂的数据类型序列

<?xml version="1.0" encoding="utf-8" ?> 
<!--Created with Liquid Studio 2017 - Developer Bundle Edition (Trial) 15.0.0.7089 (https://www.liquid-technologies.com)--> 
<xs:schema elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema"> 
    <xs:group name="location"> 
     <xs:sequence> 
      <xs:element name="city" type="xs:string" /> 
      <xs:element name="flat_num" type="xs:string" /> 
      <xs:element name="landmark" type="xs:string" /> 
      <xs:element name="street" type="xs:string" /> 
     </xs:sequence> 
    </xs:group> 
    <xs:group name="student"> 
     <xs:sequence> 
      <xs:element name="firstname" type="xs:string" /> 
      <xs:element name="lastname" type="xs:string" /> 
      <xs:element name="mothername" type="xs:string" /> 
      <xs:element name="fathername" type="xs:string" /> 
     </xs:sequence> 
    </xs:group> 
    <xs:element name="Student_details" type="details" /> 
    <xs:complexType name="details"> 
     <xs:sequence> 
      <xs:group ref="location" /> 
      <xs:group ref="student" /> 
     </xs:sequence> 
    </xs:complexType> 
</xs:schema> 

我也会质疑一个组是否最能实现你想描述的内容。你目前会产生这样的XML

<?xml version="1.0" encoding="utf-8"?> 
<!-- Created with Liquid Studio 2017 - Developer Bundle Edition (Trial) 15.0.0.7089 (https://www.liquid-technologies.com) --> 
<Student_details xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
       xsi:noNamespaceSchemaLocation="Schema.xsd"> 
    <city>string</city> 
    <flat_num>string</flat_num> 
    <landmark>string</landmark> 
    <street>string</street> 
    <firstname>string</firstname> 
    <lastname>string</lastname> 
    <mothername>string</mothername> 
    <fathername>string</fathername> 
</Student_details>
