XML creation

[Alexeev Andrey]

The problem:
Applicion (Delphi) create the XML file.
XML itself is correct.
But it's needed to add DTD file description (prolog) in the file like: <!DOCTYPE vipdata SYSTEM "vut.dtd">.
How can I add such a string in Delphi code (I'm using TXMLDocument to create XML document)
