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:complexType>
<xs:element name="customer" type="pname"/>
