SCO XENIX version numbers

[Robert Andersson]

Could some nice person out there clarify what the current SCO XENIX version
numbers are? I am just now in the process of buying both a 286 and a 386 XENIX,
and don't want to get ripped off buying old versions. From reading this 
newsgroup I have figured this might be correct:

SCO XENIX/386  2.3.1
SCO XENIX/286  2.2.3

Are these numbers correct? Do these numbers specify the base OS, 
the development system, or both?
