XML Namespace problem

[namita_jain]

Hi
I have an XML which includes two namespaces.
I am able to add one namespace
How do i add the second namespace through my code?

The sample Xml is as follows:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE vers:VERSEncapsulatedObject SYSTEM "C:\New_VERS_dtd\vers.dtd">
<vers:VERSEncapsulatedObject xmlns:vers="http://www.prov.vic.gov.au/gservice/standard/pros99007.htm" xmlns:naa="http://www.naa.gov.au/recordkeeping/control/rkms/contents.html">
    <vers:VEOFormatDescription>
        <vers:Text>Text</vers:Text>
    </vers:VEOFormatDescription>
    <vers:Version>Text</vers:Version>

The code i am writing for this is :

string lstrFileName = "C:\\TextXml.xml";
            string lstrDTDPath = "C:\\New_VERS_dtd\\vers.dtd"; 

            XmlDocument lobjXmlDoc = new XmlDocument();
            lobjXmlDoc.AppendChild(lobjXmlDoc.CreateXmlDeclaration("1.0", "UTF-8", null));
lobjXmlDoc.AppendChild(lobjXmlDoc.CreateDocumentType("vers:VERSEncapsulatedObject", null, lstrDTDPath, null));
            XmlElement RootElem = lobjXmlDoc.CreateElement("vers", "EncapsulatedObject", "http://www.prov.vic.gov.au/gservice/standard/pros99007.htm");
               
            lobjXmlDoc.AppendChild(RootElem);
            lobjXmlDoc.Save(lstrFileName);

Thanx in advance
