I tried the following with MSXML 6 (and JScript but that should not 
matter, you would just need to translate the API calls to C++):

var doc = new ActiveXObject('Msxml2.DOMDocument.6.0');
doc.appendChild(doc.createProcessingInstruction("xml", "version=\"1.0\" 
encoding=\"US-ASCII\""));
doc.appendChild(doc.createElement("foo"));
doc.documentElement.text = "Testing umlauts: äöü";
doc.save("test2009010101Output.xml");

The resulting XML document has the XML declaration and escapes the 
non-ASCII characters with character references:

<?xml version="1.0" encoding="US-ASCII"?>
<foo>Testing umlauts: &#228;&#246;&#252;</foo>

So that looks fine to me. Are you not using the save method to save your 
MSXML DOM document?
