RE: A motion for property tracking via decorations



I assumed continuous means continuous at every point where it is defined? This can be clarified. What is C1 continuous? Differentiable? This seems a very non-standard terminology, but in any case, this needs to be clarified.

	Nate,

	Some observations about your new motion:

	On page 2, 2.2 Decorations, the list of examples includes
	the entry:

		S(sqrt,[0,4]) = D3.

	This suggests to me that earlier on page 1, Definition 1,
	the continuous you are describing is C0 continuous.  Were
	it C1 continuous or anything higher the answer to sqrt([0,4])
	would be D2 (defined but NOT continuous).  In that case we
	would have:

		S(sqrt,[0,4]) = D2, &
		S(sqrt,[1,4]) = D3.
