The sed man page references XPG4 for, presumably, /usr/xpg4/bin/sed. 
man XPG4 says Solaris 7-9 support SUSv2 (POSIX.1b-1993 and 
POSIX.1c-1996) while Solaris 10 supports SUSv3 (POSIX.1-2001).  This
should happen automatically if your environment has the setting 
CONFIG_SHELL=/usr/xpg4/bin/sh as described in the PROBLEMS file.
