Example 1

The following example shows a schema, Myschama2.xsd, which contains elements defined in Myschama1.xsd. The pname type is redefined. According to this schema, elements constrained by pname 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>
