30  * <p>Title: JivanSimpleXMLObjectImpl</p>
31  * <p>Description: This class represents implementation of XMLObject interface.
32  * Its main purpose is to provide the way for creation of XMLObject object by
33  * passed Jivan org.w3c.dom.Document Jivan implementation. The XMLCObject
34  * created by this manner can be used in already existing writeDOM() methods of
35  * ServletHttpPresentationResponse object to perform http response. Note that
36  * this class was tested only in in http response, not in DOM manipulation, and
37  * some methods throw an exception
38  * because they are not implemented.</p>
