The following XML file is generated for the preceding code example.

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

Remarks

The appinfo element defines application-specific information within an annotation
