	Ah, so you place your philosophy squarely in the tracking camp.
	Good.

	You are correct.  I was unclear whether you were espousing
	a tracking or static philosophy.  I hope I am clear on that
	now.

	Ah, but my amendment has nothing to do with my understanding
	or misunderstanding of your philosophy of decorations.

	I merely move to amend the motion to remove bits & details
	of implementation that clearly do not belong at level 1.
	And, further, to make explicit the partial ordering that is
	required for FTDIA to be proven.

	Issues of tracking versus static can wait until we discuss
	the merits of your motion.  And I can go either way on that
	so long as I am clear just WHICH way we are going.

	So, given that, will you now accept my amendment as friendly?
