</employee> The schema is expecting that we qualify the globally declared attribute name. It wants to see the following: <?xml version = "1.0" ?> <employee xmlns = "http://www.wbex.ru/employees"

If the schema had a value of unqualified for elementFormDefault it would look like so RussianDoll_eu_au.xml

   <source lang="xml">

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

       targetNamespace = "http://www.wbex.ru/employees"
       xmlns:cust = "http://www.wbex.ru/employees"
       elementFormDefault = "unqualified"
       attributeFormDefault = "unqualified">
  
  <element name = "employee">
     <complexType>
        <sequence>
        <element name = "FirstName" type = "string" />
        <element name = "MiddleInitial" type = "string" 
                 minOccurs = "0" maxOccurs = "1" />
        <element name = "LastName" type = "string" />
        </sequence>
        <attribute name = "employeeID" use = "required" type = "integer" />
        <attribute name = "clubCardMember" type = "boolean" />
     </complexType>
  </element>

</schema> File: Data.xml

<?xml version = "1.0" ?> <cust:employee xmlns:cust = "http://www.wbex.ru/employees" 

              employeeID = "2442"
              clubCardMember = "true" >
  <FirstName>first</FirstName>
  <MiddleInitial>middle</MiddleInitial>
  <LastName>last</LastName>

</cust:employee>

Requiring All Elements and Attributes Be Qualified

   <source lang="xml">

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

       targetNamespace = "http://www.wbex.ru/employees"
       xmlns:cust = "http://www.wbex.ru/employees"
       elementFormDefault = "qualified"
       attributeFormDefault = "qualified">
  
  <element name = "employee" type = "cust:employeeType" />
  
  <complexType name = "employeeType">
     <sequence>
        <element name = "FirstName" type = "string" />
        <element name = "MiddleInitial" type = "string" />
        <element ref = "cust:LastName" />
     </sequence>
     <attribute name = "clubCardMember" type = "boolean" />
     <attribute ref = "cust:employeeID" />
  </complexType>
  
  <element name = "LastName" type = "string" />
  <attribute name = "employeeID" type = "integer" />

</schema> We could qualify each element and attribute individually like so: <?xml version = "1.0" ?> <cust:employee xmlns:cust = "http://www.wbex.ru/employees" 

              cust:clubCardMember = "true" 
              cust:employeeID = "24427">
  <cust:FirstName>Ray</cust:FirstName>
  <cust:MiddleInitial>G</cust:MiddleInitial>
  <cust:LastName>Bayliss</cust:LastName>

</cust:employee> But the following would NOT be valid: <?xml version = "1.0" ?> <employee xmlns = "http://www.wbex.ru/employees" 

         clubCardMember = "true" 
         employeeID = "24427">
  <FirstName>first</FirstName>
  <MiddleInitial>middle</MiddleInitial>
  <LastName>last</LastName>

</employee> 

</source>


using local element declarations for the children of the employee element

   <source lang="xml">

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

       targetNamespace = "http://www.wbex.ru/employees"
       xmlns:cust = "http://www.wbex.ru/employees">
  
  <element name = "employee" type = "cust:employeeType" />
  
  <complexType name = "employeeType">
     <sequence>
        <element name = "FirstName" type = "string" />
        <element name = "MiddleInitial" type = "string" />
        <element name = "LastName" type = "string" />
     </sequence>
  </complexType>

</schema> The following will not work in an instance document, because we are only expected to qualify globally declared elements and attributes. <?xml version = "1.0" ?> <employee xmlns = "http://www.wbex.ru/employees"> 

  <FirstName>Ray</FirstName>
  <MiddleInitial>G</MiddleInitial>
  <LastName>Bayliss</LastName>

</employee> The proper way of showing this in a document is: <?xml version = "1.0" ?> <cust:employee xmlns:cust = "http://www.wbex.ru/employees"> 

  <FirstName>first</FirstName>
  <MiddleInitial>middle</MiddleInitial>
  <LastName>last</LastName>

</cust:employee>
