Justa aclosure..

I workd arround the answer by using createNode function insted of
createElement:

IXMLDOMElement parent = thisXDocument.DOM.selectSingleNode("place to add");

IXMLDOMElement my_AgendaItem = thisXDocument.DOM.createNode(1,
"my:AgendaItem", parent.namespaceURI);

parent.appendChild(my_AgendaItem);
