Adding DTD reference in xml

Question

hi,
      This way i am creating xml,
        var cAcrobat += "<Root>";
        cAcrobat += "<Sample>" + "Something" + "</Sample>";
        cAcrobat += "</Root>";
        this.createDataObject("Acrobat.xml", cAcrobat);
        var Acrobat = this.getDataObjectContents("Acrobat.xml");
        cAcrobat = util.stringFromStream(Acrobat,  "utf-8");
        var myXML = XMLData.parse(cAcrobat, false);
        var cAcrobat = myXML.saveXML('pretty');
        var Acrobat = util.streamFromString(cAcrobat, "utf-8");
        this.setDataObjectContents("Acrobat.xml", Acrobat);
and as a result it is creating an xml file as an attachment to pdf,  as follows,
  <?xml version="1.0" encoding="UTF-8" ?>
- <xfa:data xmlns:xfa="http://www.xfa.org/schema/xfa-data/1.0/">
- <Root>
  <Sample>Something</Sample>
  </Root>
  </xfa:data>
but i want to add DTD reference to xml file before the Root node  and after adding it should create xml like this,
<?xml version="1.0" encoding="UTF-8" ?>
"<!DOCTYPE  Some-application SYSTEM 'file:C:/SomeFolder/Test.dtd'>";
- <xfa:data xmlns:xfa="http://www.xfa.org/schema/xfa-data/1.0/">
- <Root>
  <Sample>Something</Sample>
  </Root>
  </xfa:data>
please tell me how to add this dtd reference in xml file, and whater i am doing above is correct or not?
