== Set attributeFormDefault to qualified==<br />
<br />
<br />
<br />
<br />
<!-- start source code --><br />
<br />
<source lang="xml"><br />
<xsd:schema<br />
xmlns:xsd="http://www.w3.org/2001/XMLSchema"<br />
targetNamespace="http://www.wbex.ru/namespaces/employee"<br />
xmlns="http://www.wbex.ru/namespaces/employee"<br />
elementFormDefault="qualified"<br />
attributeFormDefault="qualified"><br />
<xsd:element name="employee"><br />
<xsd:complexType><br />
<xsd:sequence><br />
<xsd:element name="name" type="xsd:string"/><br />
<xsd:element name="email" type="xsd:string"/><br />
<xsd:element name="hireDate" type="xsd:string"/><br />
</xsd:sequence><br />
<xsd:attribute name="dept" type="xsd:string"/><br />
<xsd:attribute name="client" type="xsd:string"/><br />
</xsd:complexType><br />
</xsd:element><br />
</xsd:schema><br />
We have set both attributes to qualified; therefore, all elements and attributes in our instance document must be qualified:<br />
<em:employee<br />
xmlns:em="http://www.wbex.ru/namespaces/employee"<br />
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"<br />
xsi:schemaLocation="http://www.wbex.ru/namespaces/employee employee.xsd"<br />
em:dept="programming"<br />
em:client="Smith and Co"><br />
<em:name>Joe Smith</em:name><br />
<em:email>a@a.ru</em:email><br />
<em:hireDate>2008-10-29</em:hireDate><br />
</em:employee><br />
If we set elementFormDefault to qualified and omit attributeFormDefault (its default value is unqualified), <br />
we could use the following document instance:<br />
<em:employee<br />
xmlns:em="http://www.wbex.ru/namespaces/employee"<br />
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"<br />
xsi:schemaLocation="http://www.wbex.ru/namespaces/employee employee.xsd"<br />
dept="programming"<br />
client="Smith and Co"><br />
<em:name>Joe Smith</em:name><br />
<em:email>a@a.ru</em:email><br />
<em:hireDate>2008-10-29</em:hireDate><br />
</em:employee></source><br />
