As the systems below show, the grammatico-semantic model assumes a bijective or one-to-one relation between LG features and semantic features. What differs is the intrastratal relations between the features. The semantic networks appear to re-systemicise the LG systems.Crucially, the names given to the semantic features imply moves in unfolding exchanges. They are therefore potentially complementary with the exchange systems first proposed by Margaret Berry and further developed in ET as the discourse semantic system of NEGOTIATION.

[1] This misleading, because it is not true. As Table 24.4 details, the semantic feature 'alternative' has multiple systemic lexicogrammatical realisations.
[2] To be clear, a semantic network represents a higher level of symbolic abstraction than a lexicogrammatical network.
[3] The implication here is misleading. To be clear, Halliday's system of SPEECH FUNCTION, part of which Hasan (1983) develops in Figure 24.4, has always been concerned with 'moves in unfolding exchanges'. The title of the chapter on mood in IFG, has always been 'clause as exchange'.
[4] This is very misleading indeed. The original work is by Halliday and Hasan. The reason why the work of Berry and Martin is "complementary" is that both are based on the original work. Rose's wording falsely suggests that they are parallel independent developments. For a close examination of Martin's system of NEGOTIATION, see here (English Text) and here (Working With Discourse).
