The various versions of XPG are unix standards; POSIX is supposed to be a standard for an OS, and many operating systems can be POSIX- compliant (e.g., VMS, Windows/NT, some IBM OSes). The XPG standards are closer to SysV than BSD. XPG4 is pretty much a strict superset of POSIX 1003.1, and hopefully 1003.2, although I don't know for certain about the latter.
