Halliday & Matthiessen (2014: 620):
Here cohesion is established by reference to the ‘matter’ that has gone before. As noted earlier, many expressions of matter are spatial metaphors, involving words like point, ground, field; and these become conjunctive when coupled with reference items. The relation is either (i) positive or (ii) negative. Examples:
(i) positive:||| Without chlorine in the antarctic stratosphere, || there would be no ozone hole. ||| (Here “hole” refers to a substantial reduction below the naturally occurring concentration of ozone over Antarctica.) |||
(ii) negative: in other respects, elsewhere||| The serial dilutions of the serum are made in AB serum || and the standard cells are suspended in 30 per cent bovine albumin. ||| In all other respects the method is identical with technique No. 17. |||

* Strictly speaking, 'matter' is a category of projection, not expansion: enhancement.
