There is nothing like POSIX 1 or 2. There is POSIX.1-1988 (the oldest)
there is one from 1990 1992, ... 

Before POSIX.1-2001, the POSIX standard was not usable to define a system as
it did not include a sufficient amount of definitions. This is why there has
been UNIX-95 (SUSv1) and UNIX-98 (SUSv2) from the OpenGroup. POSIX.1-2001 is
the first POSIX standard that was no longer from IEEE but from the OpenGroup
and it was first approved as SUSv3). VMS/VAX is e.g. not even SUSv2 compliant
as it does not include a scalar int64_t in inttypes.h.

SUSv2 is IIRC the first standard that included programs like ls tar sh 
and thus described a complete system and not only few constraints.

BTW: SUSv2 aready desribes the korn shell as "sh"

There later was a hard discussion as in 1998 ksh was not OpenSource.
David Korn then has a hard fight with AT&T and finally around 2001
was able to present ksh93 as true OSS (compliant to
http://www.opensource.org/docs/definition.php). As it was hard to get 
the permission for ksh93, the name will not change in future ;-)
