  Add XKB_KEYSYM_MIN and XKB_KEYSYM_MAX Keysyms are 32-bit integers with the 3 most significant bits always set to zero. See: Appendix A “KEYSYM Encoding” of the X Window System Protocol at https://www.x.org/releases/current/doc/xproto/x11protocol.html#keysym_encoding. Add a new constants XKB_KEYSYM_MIN and XKB_KEYSYM_MAX to make the interval of valid keysyms more obvious in the code.
