The experimental block is spacious, with 128 values, so I highly recommend to anyone doing actual experiments involving administrative records (e.g., I believe both the BIBE and compressed status reporting do) that they use code points in this reserved block rather than choose some other unallocated value(s) and hope that reality does not collide with their prototypes.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>The point of private use and experimental reservations are to guarantee that no well-behaving user, operating with registered code points, will collide with your use.
