Nameprep was designed so that if Unicode evolves in a backward compatible way (new characters added, old normalization mappings unchanged), then Nameprep can evolve along with it in a backward compatible way, with no need to change the ACE prefix. (Actually Unicode normalization did change in an incompatible way between 3.2 and 4.0 when five erroneous compatibility mappings were fixed, but the NormalizationCorrections.txt file allows applications to choose whether to keep the errors for backward compatibility. A new Nameprep would have to specify which choice to make.) AMC
