    30 * Instance of TXmlEngBinaryContainer class represents binary data in 
    31 * DOM tree.
    32 *
    33 * Binary data is treated in general as text nodes in DOM tree. 
    34 * Some of the fields in xmlNode structure are reused in order to save memory. 
    35 * Data is stored in process's heap memory.
    36 *
    37 * Sample code for creating binary container:
    38 * @code  
    39 *      RXmlEngDOMImplementation domImpl;
    40 *      domImpl.OpenL();        ///< opening DOM implementation object 
    41 *      RXmlEngDocument iDoc; 
    42 *      ///< create document element
    43 *      TXmlEngElement elem = iDoc.CreateDocumentElementL(_L8("doc"));
    44 *      ///< create binary container from buffer (str1) and CID equals cid
    45 *      TXmlEngBinaryContainer binData=iDoc.CreateBinaryContainerL(cid,*str1);  
    46 *      elem.AppendChildL(binData);      ///< append container to the dom tree       
    47 *      iDoc.Close();               ///< closing all opened objects
    48 *      domImpl.Close();
    49 * @endcode
