Exception when using ImportXml

I have created a basic form in Designer 8 and saved the form as type Acrobat 7. The form contains 2 text fields and a submit button that submits data as XML. Following is the XML the form submits:

<?xml version="1.0" encoding="UTF-16"?>
<form1>
  <TextField1>texta</TextField1>
  <TextField2>textb</TextField2>
</form1>

When using the below routine, Aspose ImportXml() throws exception “Invalid xml format: expected FIELDS node element!” This seems that ImportXml is trying to import XFDF. Is this a possible bug?

private void ImportMyXml()
{
    string inputFilePath = @"D:\qatest.m.qa-00208.pdf";
    string outputFilePath = inputFilePath.Replace(".pdf", "_out.pdf");
    string xmlFilePath = inputFilePath.Replace(".pdf", ".xml");

    FileStream xmlInputStream = new FileStream(xmlFilePath, FileMode.Open);

    Aspose.Pdf.Kit.Form form = new Aspose.Pdf.Kit.Form(inputFilePath, outputFilePath);

    //Import the values from the XML file to the PDF form
    form.ImportXml(xmlInputStream);

    //Save the output PDF document
    form.Save();

    xmlInputStream.Close();
}

Thanks for reporting this issue that is reproduced on my testbed.
