为前面的代码示例生成以下 XML 文件。

<?xml version="1.0" encoding="IBM437"?>
<xs:schema  xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <xs:element name="State">
        <xs:annotation>
            <xs:documentation>State Name</xs:documentation>            
            <xs:appinfo>Application Information</xs:appinfo>
        </xs:annotation>
    </xs:element>
</xs:schema>
