From my understanding of the System V Interface Definition, along with its
eventual validation suite, and my experience with AT&T's System V URTS
(the 68000 System V microport validation, completed almost a year ago):  The
System V Interface Definition addresses the "fundamentals" of System V (and then
there are extensions, a la /usr/group standards).  Since these fundamentals form
a (large) subset of System V, its validation suite will not encompass all that
URTS does.  Xenix is only being challenged to pass the System V Interface test,
*not* URTS/etc.
	This latter, URTS/etc., validates conformance to requirements/
specifications above and beyond the Interface Definition.  Moreover, the
generic microport validation involves more than URTS; it also involves a
line-by-line justification of every change to source code.  It should be true,
therefore, that every validated microport has, by definition, also passed a
System V "Interface" test.
	Nevertheless, Microsoft's commitment to meeting/passing the System V
Interface test is a great boost for Un*x standards and the Un*x-based
applications software business.
