   388 	/** Updates a remote selection of id  with relevant data when called by the Message Server.

   389 	 

   390 	Implementations should provide this function if the messaging protocol supports 

   391 	updating of remote entries. If this is not supported, implementations should 

   392 	leave with KErrNotSupported. 

   393 	

   394 	The Server-side MTM implementation must decide what information in the TMsvEntry 

   395 	is relevant to the remote entry, and translate it appropriately for the specific 

   396 	protocol. Most of the data contained in the TMsvEntry is specific to the Symbian 

   397 	OS Message Server, and would probably have no direct correlation with the 

   398 	protocol's own storage format. Some entry data may however be useful. For 

   399 	example, if the protocol supports remote renaming of folders, the implementation 

   400 	could:

   401 	

   402 	1. check for a folder type entry

   403 	

   404 	2. extract the folder name from aNewEntry.iDetails

   405 	

   406 	3. check if the folder name has changed by comparing the new name with iDetails 

   407 	in the index entry currently; if not, complete with KErrNone

   408 	

   409 	4. initiate a protocol-specific action to rename the remote folder

   410 	

   411 	The implementation should also always update the local Message Server index 

   412 	through CMsvServerEntry::ChangeL().

   413 	

   414 	@param aSelection  Selection of TMsvId which to update 

   415 	@param aMark Read and Unread mark value. 

   416 	@param aStatus Asynchronous completion word for the operation. 

   417 	

   418 	@leave KErrNotSupported The Server-side MTM does not support this operation 

   419 	@leave Other leave codes Dependent on implementation */
