	John,

	While I don't think we should have bare objects of any kind,
	I agree with Nate on this point.  But for a different reason.

	If we should promote bare decorations to anything other than
	empty, we risk violating inclusion isotonicity &, therefore,
	violating FTDIA.

	It is my opinion that this risk is entirely due to the mixing
	of bare objects with 'true' intervals but the risk is there
	whatever your opinion of their utility.

	Yours,

				   Dan
