Halliday & Matthiessen (2014: 648):
The occurrence of any pair of items within the set will be cohesive; for example
||| On the left of the park lies the Exhibition Centre [[ which covers a massive 25,000 square metres of column-free space under the one roof]] . ||| Opened in January 1988, || the Centre is designed to hold major international exhibitions. ||| The glassed eastern facade is stepped back in five separate stages [[ that can be partitioned off to form smaller halls]]. ||| The fifth hall is linked by covered walkway to the Convention Centre. |||
||| Elfrida had a beautiful little glass scent-bottle. ||| She had used up all the scent long ago; || but she often used to take the little stopper out ||| ...
||| She knelt down || and looked along the passage into the loveliest garden [[ you ever saw]] . ||| How she longed to get out of that dark hall, || and wander about among those beds of bright flowers and those cool fountains, || ...
where roof, facade, hall are meronyms of centre, stopper is a meronym of bottle, and flowers and fountains are co-meronyms of garden.
