* 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).
