8. A first Extensible Markup Language (XML) Document Management (XDM) Client Device for managing an XDM Server history in an XDM Server, the XDM Server being a XML Document Management Server, the first XDM Client Device comprising: a processor configured to set Filtering Rules within a filter body in an XCAP request, wherein the set Filtering Rules define operation information performed on specific XML Documents to store as history information and further define when to store the history information of the XML Documents; a transmitter configured to send the XML Documents along with the set Filtering Rules to the XDM Server so that when a second XDM Client Device accesses and performs one or more operations on the XML Documents stored at the XDM Server, history information of the XML Documents can be stored in the XDM Server according to the set Filtering Rules and the one or more operations performed; and a receiver configured to receive a response from the XDM Server after the Filtering Rules are stored in the XDM Server.
