* Description:  MNssGetTagReference Client is the public callback interfaces for
*                clients that want to retrieve tag references from the VAS Db.
*                The client must inherit and override the GetTagCompleted() and
*                GetTagFailed() methods to handle VAS Db responses for
*                retrieving tag reference(s).
