<xsd:schema
  xmlns:xsd="http://www.w3.org/2001/XMLSchema"
  targetNamespace="http://www.java2s.com/namespaces/employee"
  xmlns="http://www.java2s.com/namespaces/employee"
  elementFormDefault="qualified"
  attributeFormDefault="qualified">
  <xsd:element name="employee">
   <xsd:complexType>
    <xsd:sequence>
     <xsd:element name="name" type="xsd:string"/>
     <xsd:element name="email" type="xsd:string"/>
     <xsd:element name="hireDate" type="xsd:string"/>
    </xsd:sequence>
    <xsd:attribute name="dept" type="xsd:string"/>
    <xsd:attribute name="client" type="xsd:string"/>
   </xsd:complexType>
  </xsd:element>
</xsd:schema>

We have set both attributes to qualified; therefore, all elements and attributes in our instance document must be qualified:

<em:employee
  xmlns:em="http://www.java2s.com/namespaces/employee"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://www.java2s.com/namespaces/employee employee.xsd"
  em:dept="programming"
  em:client="Smith and Co">
  <em:name>Joe Smith</em:name>
  <em:email>a@a.com</em:email>
  <em:hireDate>2008-10-29</em:hireDate>
</em:employee>

If we set elementFormDefault to qualified and omit attributeFormDefault (its default value is unqualified), 
we could use the following document instance:

<em:employee
  xmlns:em="http://www.java2s.com/namespaces/employee"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://www.java2s.com/namespaces/employee employee.xsd"
  dept="programming"
  client="Smith and Co">
  <em:name>Joe Smith</em:name>
  <em:email>a@a.com</em:email>
  <em:hireDate>2008-10-29</em:hireDate>
</em:employee>
