I am a newbie to Castor. I downloaded all the jar files, made changes
to the classpath etc, but I keep on getting exceptions being thrown.

The XML schema file is as follows:
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <xsd:element name="catalog">
    <xsd:complexType>
      <xsd:sequence>
        <xsd:element name="book" minOccurs="0" maxOccurs="unbounded">
          <xsd:complexType>
            <xsd:sequence>
              <xsd:element name="author" type="xsd:string"/>
              <xsd:element name="title" type="xsd:string"/>
              <xsd:element name="genre" type="xsd:string"/>
              <xsd:element name="price" type="xsd:float"/>
              <xsd:element name="publish_date" type="xsd:date"/>
              <xsd:element name="description" type="xsd:string"/>
            </xsd:sequence>
            <xsd:attribute name="id" type="xsd:string"/>
           </xsd:complexType>
          </xsd:element>
      </xsd:sequence>
    </xsd:complexType>
  </xsd:element>
</xsd:schema>

If I type in:
C:\>java org.exolab.castor.builder.SourceGenerator -i
C:\\Temp\\Test.xsd

I get the error message:
Exception in thread "main" java.lang.IllegalArgumentException: The
prefix 'xml' is reserved (XML 1.0 Specification) and cannot be
declared.
