    1.34 +* Instance of TXmlEngChunkContainer class represents data stored in RChunks in DOM tree
    1.35 +*
    1.36 +* RChunk data is treated in general as text nodes in DOM tree.
    1.37 +* Some of the fields in xmlNode structure are reused in order to save memory. 
    1.38 +* Data is stored in memory referenced to by RChunk.
    1.39 +*
    1.40 +* Sample code for creating chunk container:
    1.41 +* @code  
    1.42 +*      RXmlEngDOMImplementation domImpl;
    1.43 +*      domImpl.OpenL();        ///< opening DOM implementation object 
    1.44 +*      RXmlEngDocument iDoc; 
    1.45 +*      ///< create document element
    1.46 +*      TXmlEngElement elem = iDoc.CreateDocumentElementL(_L8("doc"));
    1.47 +*      ///< create RChunk object with chunkName name and size
    1.48 +*      RChunk chunk;
    1.49 +*      chunk.CreateGlobal(chunkName, size, maxSize);
    1.50 +*      CleanupClosePushL(chunk); 
    1.51 +*      ///< create chunk container from Rchunk object with offset to the 
    1.52 +*      ///< binary data in chunk and binary data size in chunk (binarySize) 
    1.53 +*      TXmlEngChunkContainer binData = iDoc.CreateChunkContainerL(
    1.54 +*									cid,chunk,offset,binarySize); 
    1.55 +*      ///< append chunkcontainer to the dom tree          
    1.56 +*      TXmlEngNode ref = iDoc.DocumentElement().AppendChildL(binData);
    1.57 +*       ///< closing all opened objects
    1.58 +*      CleanupStack::PopAndDestroy();//chunk
    1.59 +*      iDoc.Close();
