Martin (1992: 26):
The chapters which follow are organised in the following way. Chapters 2, 3, 4 and 5 deal with the four central discourse systems constituting the discourse semantic stratum proposed: NEGOTIATION, IDENTIFICATION, CONJUNCTION and IDEATION respectively. These chapters are organised by metafunction: NEGOTIATION considers the discourse semantics of interpersonal meaning, IDENTIFICATION the discourse semantics of textual meaning, CONJUNCTION the discourse semantics of logical meaning, and IDEATION the discourse semantics of experiential meaning.

[1] As will be demonstrated, Martin's interpersonal system of NEGOTIATION is his rebranding of Halliday's interpersonal system of SPEECH FUNCTION, and later developments of that system carried out by colleagues using Halliday's model. Of Martin's discourse semantic systems, it is the only genuine semantic system, the other three systems being his rebrandings of Halliday & Hasan's systems of cohesion, which are non-structural textual resources of the lexicogrammatical stratum.
[2] As will be demonstrated, Martin's textual discourse semantic system of IDENTIFICATION is his rebranding of Halliday's textual lexicogrammatical system of REFERENCE, confused with 'reference' in the sense of ideational denotation. That is, Martin's system confuses both strata and metafunctions.
[3] As will be demonstrated, Martin's logical discourse semantic system of CONJUNCTION is his rebranding of Halliday's textual lexicogrammatical system of COHESIVE CONJUNCTION, confused with Halliday's logical lexicogrammatical system of CLAUSE COMPLEXING. Again, Martin's system confuses both strata and metafunctions.
[4] As will be demonstrated Martin's experiential discourse semantic system of IDEATION is his rebranding of Halliday's textual lexicogrammatical system of LEXICAL COHESION, confused with his misapplications of Halliday's expansion relations to clause and group structure. Again, Martin's system confuses both strata and metafunctions.
