/**
* Instance of TXmlEngBinaryContainer class represents binary data in 
* DOM tree.
*
* Binary data is treated in general as text nodes in DOM tree. 
* Some of the fields in xmlNode structure are reused in order to save memory. 
* Data is stored in process's heap memory.
*
* Sample code for creating binary container:
* @code  
*      RXmlEngDOMImplementation domImpl;
*      domImpl.OpenL();        ///< opening DOM implementation object 
*      RXmlEngDocument iDoc; 
*      ///< create document element
*      TXmlEngElement elem = iDoc.CreateDocumentElementL(_L8("doc"));
*      ///< create binary container from buffer (str1) and CID equals cid
*      TXmlEngBinaryContainer binData=iDoc.CreateBinaryContainerL(cid,*str1);  
*      elem.AppendChildL(binData);      ///< append container to the dom tree       
*      iDoc.Close();               ///< closing all opened objects
*      domImpl.Close();
* @endcode 
*
* @lib XmlEngineDOM.lib
