The code points registered with CSUR were used for the interchange. But, to clarify, CSUR is not an official supplement to The Unicode Standard. Of course, any exchange of PUA data requires an agreement between senders and recipients. CSUR offers character mappings which private individuals may agree to use for data exchange.
