Java HTML/XML - 如何将未转义的XML写入XMLStreamWriter

import java.io.OutputStream;
import java.io.OutputStreamWriter;

import javax.xml.stream.XMLOutputFactory;
import javax.xml.stream.XMLStreamWriter;

public class Main {

  public static void main(String[] args) throws Exception {
    OutputStream stream = System.out;

    XMLOutputFactory xof = XMLOutputFactory.newFactory();
    XMLStreamWriter xsw = xof.createXMLStreamWriter(stream);

    xsw.writeStartDocument();
    xsw.writeStartElement("foo");
    xsw.writeStartElement("bar");

    xsw.writeCharacters("");
    xsw.flush();

    OutputStreamWriter osw = new OutputStreamWriter(stream);
    osw.write("<baz>Hello World<baz>");
    osw.flush();

    xsw.writeEndElement();
    xsw.writeEndElement();
    xsw.writeEndDocument();
    xsw.close();
  }

}
