The following example shows a schema, Myschama2.xsd, with elements specified by the Myschama1.xsd. The pname type is redefined. According to this schema, elements constrained by the pname type must end with a "country" element:
Myschema1.xsd:
<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:complexType name="pname">
<xs:sequence>
<xs:element name="firstname"/>
<xs:element name="lastname"/>
</xs:sequence>
</xs:complexType>
<xs:element name="customer" type="pname"/>
</xs:schema>
Myschema2.xsd:
<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:redefine schemaLocation="Myschema1.xsd">
<xs:complexType name="pname">
<xs:complexContent>
<xs:extension base="pname">
<xs:sequence>
<xs:element name="country"/>
</xs:sequence>
</xs:extension>
</xs:complexContent>
</xs:complexType>
</xs:redefine>
