It does seem inconsistent to have letters delimiting all the other
parameters except the slices. If you can come up with a different
letter for "slice" which doesn't sound too contrived, I'd prefer
that. Right now 's' could be either "subdevice" or "slice". One could
use 'l' for discLabel, but that looks too much like '1'.
