SP Gugu: How to Programmatically change a list item's ContentType by WSS WebService?

Please, help! I can't find any information on MSDN under WSS3 webservices List.UpdateListItems topics

how to programmatically change a list item ContentTypeId ?

Calling SharePoint list service like: (adding a list item)

XmlElement elBatch = doc.CreateElement("Batch");

elBatch.SetAttribute("OnError", "Continue");

elBatch.SetAttribute("ListVersion", "2");

XmlElement el1 = doc.CreateElement("Method");

el1.SetAttribute("ID", "1");

el1.SetAttribute("Cmd", "New");

XmlElement field1 = doc.CreateElement("Field");

field1.SetAttribute("Name", "ID");

field1.InnerText = "New";

XmlElement field2 = doc.CreateElement("Field");

field2.SetAttribute("Name", "emp_no");

XmlNode response = listService.UpdateListItems("Tasks", elBatch);

In order to update metadata you need to specify reference to the file that you want to update, here I found answer to my question:

For me goal was to upload files to Sharepoint Programmatically and update metadata (Indexes, Column information) using Web Services.

What is the corresponding way to set an SPListItem's ContentType directly using the WSS object model?
