> The Codec based strip of tags was done as a temp solution not to pass the critical system tags from server back to client. This also imposes the limitation that Tags can not be used by users. Tags are a system side feature alone. In the past there were some Qs in user@ for using custom tags. 
> We should allow users to set tags on Cell and pass them while write. Also these custom tags must be returned back to users (Irrespective of codec and all). The system tags (like ACL, visibility) should not get transferred btw client and server. And when the client is run by a super user, we should pass all tags (including system tags). This way we can make sure that all tags are passed while replication and also tool like Export gets all tags.
