Creating Vocabularies that Belong to a Namespace

   <source lang="xml">

File: Schema.xsd <?xml version = "1.0" ?> <xs:schema xmlns:xs = "http://www.w3.org/2001/XMLSchema"

          targetNamespace = "http://www.wbex.ru/Customers"
          xmlns = "http://www.wbex.ru/Customers">
  
  <xs:element name = "Customer" >
     <xs:complexType>
        <xs:sequence>
           <xs:element name = "FirstName" type = "xs:string" />
           <xs:element name = "MiddleInitial" type = "xs:string" />
           <xs:element ref = "LastName" />
        </xs:sequence>
     </xs:complexType>
  </xs:element>
  
  <xs:element name = "LastName" type = "xs:string" />
  

</xs:schema> File: Data.xml <?xml version = "1.0" ?> <cust:Customer xmlns:cust = "http://www.wbex.ru/Customers"

              xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance"
              xsi:schemaLocation = "Schema.xsd">

Creating Vocabularies that Do Not Belong to a Namespace

   <source lang="xml">

File: Schema.xsd <?xml version = "1.0" ?> <xs:schema xmlns:xs = "http://www.w3.org/2001/XMLSchema">

  <xs:element name = "Customer" >
     <xs:complexType>
        <xs:sequence>
           <xs:element name = "FirstName" type = "xs:string" />
           <xs:element name = "MiddleInitial" type = "xs:string" />
           <xs:element name = "LastName" type = "xs:string" />
        </xs:sequence>
     </xs:complexType>
  </xs:element>
  

</xs:schema> A conforming instance document would look something like this: <?xml version = "1.0" ?> <Customer xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance"

         xsi:noNamespaceSchemaLocation = "Schema.xsd">
  
  <FirstName>first</FirstName>
  <MiddleInitial>middle</MiddleInitial>
  <LastName>last</LastName>

</Customer>

Looking Behind Namespace Qualification

   <source lang="xml">

File: Schema.xsd <?xml version = "1.0" ?> <xs:schema xmlns:xs = "http://www.w3.org/2001/XMLSchema"

          xmlns = "http://www.wbex.ru/Customers">
  
  <xs:element name = "Customer" type = "CustomerType" />
  <xs:complexType name = "CustomerType">
     <xs:sequence>
        <xs:element name = "FirstName" type = "xs:string" />
        <xs:element name = "MiddleInitial" type = "xs:string" />
        <xs:element ref = "LastName" />
     </xs:sequence>
     <xs:attribute name = "clubCardMember" type = "xs:boolean" />
     <xs:attribute ref = "customerID" />
  </xs:complexType>
  <xs:element name = "LastName" type = "xs:string" />
  <xs:attribute name = "customerID" type = "xs:integer" />
  

</xs:schema> File: Data.xml <?xml version = "1.0" ?> <cust:Customer xmlns:cust = "http://www.wbex.ru/Customers"

              clubCardMember = "true" 
              cust:customerID = "24427">
  <FirstName>first</FirstName>
  <MiddleInitial>middle</MiddleInitial>
