	Well, youre the chair of the DM group, so you have the power to decide
	to 'not do' something, but..

	I would have thought this a DM exercise as systems of units are already
	well quantified, and there is little, to no, slipperiness in the meaning
	of, or definition of the units themselves. Furthermore, the real 'issue'
	in units seems to be which representations to choose, and which
	system(s) are allowed rather than 'what units mean'.
