Sure. There is no standard how to map the Unicode properties to POSIX
character classes. Other than the mentioned ISO C constraints for
'digit' and 'xdigit' and a few POSIX constraints, you are free to
map them as you like. For glibc and gnulib, I mapped them in a way
that seemed to make most sense for applications. But different
people might come to different meanings of "make sense".
