[1] To be clear, parataxis and hypotaxis do not describe relations between elements in function structures. Rather, parataxis and hypotaxis are degrees of interdependency between formal units in unit complexes: between clauses in clause complexes, between groups/phrases in group/phrase complexes, and between words in word complexes; see Halliday & Matthiessen (2014: 451).
[2] To be clear, it is true that, in SFL Theory, interdependency relations obtain in univariate structures, and not in multivariate structures. This means that they obtain in the iterative structures that realise the logical metafunction.
On the other hand, Doran's notion of "potential for iteration" derives from his previous misconstrual of "iterated" elements as an iterative structure. It will soon be seen that this misunderstanding forms the basis of his next argument.
