[1] To be clear, this table presents the four cells of the preceding table as 'iterative'.
In the case of the top cell of the 'iterative' column, [non-linear, non-nuclear], this is consistent with SFL Theory, since parataxis is one type of interdependency relation in iterative structures of the logical metafunction.
In the case of the second cell of the 'iterative' column, [non-linear, nuclear], this is not consistent with SFL Theory, because, as previously explained, Doran's 'iteration' confuses multiple occurrences of (experiential) elements — Epithets, Qualifiers, circumstances — with iterative structures of the logical metafunction.
In the case of the third cell of the 'iterative' column, [linear, non-nuclear], this is not consistent with SFL Theory, not least because 'covariate' is not a type of structure, as Lemke (1989) acknowledges.
In the case of the bottom cell of the 'iterative' column, [linear, nuclear], this would be consistent with SFL Theory, if hypotaxis had been what Doran argued for, since hypotaxis is one type of interdependency relation in iterative structures of the logical metafunction. However, Doran's argument for this classification was actually concerned with the relation between Classifiers in the experiential structure of the nominal group.
This bottom cell also features a category for which there has been no argumentation, 'phoric covariate'. Again, the problem here is that 'covariate' is not a type of structure, and so not iterative in a structural sense.
[2] The 'non-iterative' column of the table has only two of its four cells filled.
The upper cell, [non-linear, nuclear], is consistent with SFL Theory in as much as experiential structures are multivariate and so non-iterative.
However, the lower cell, [linear, nuclear], identifies the subjacency duplex. On the one hand, there has been no argument for classifying this structure as linear, and on the other hand, the subjacency duplex is not a structure, not least because it is based on misunderstandings of constituency.
