To me personally, that sounds wrong.  I would have thought that a test
proper could only PASS or FAIL.  Decisions that the system is broken
being kept separate vis:

	if necessary setup xfail
	perform the test

People have talked about ripping out XFAIL and moving that information
to a separate database.  If tests start to contain implicit decisions to
XFAIL then that operation is going to be very hard.
