[37] The Problem With Covariate Structures
Blogger Comments:
“discourse” is text that is being viewed in its sociocultural context, while “text” is discourse that is being viewed as a process of language.
The system and the text are not two different phenomena: what we call the “system” of a language is equivalent to its “text potential”. Analysing discourse means, first and foremost, relating the text to the potential that lies behind it.
A text is meaningful because it is an actualisation of the potential that constitutes the linguistic system; it is for this reason that the study of discourse (‘text linguistics’) cannot properly be separated from the study of the grammar that lies behind it.
The “textual” metafunction is the name we give to the systematic resources a language must have for creating discourse: for ensuring that each instance of text makes contact with its environment. The “environment” includes both the context of situation and other instances of text.
My own 'covariate structure' (Lemke 1985), which includes Halliday's univariate type, is for the case of homogeneous relations of co-classed units, and should perhaps be called a 'structuring principle' rather than a kind of structure.
Martin's covariate structures are not structures in the sense of units with internal structure, nor in the sense of units forming complexes.

[4] Misrepresenting SFL On Structural Subtypes
Doran (2021):
Blogger Comments:
This is misleading, because it is not true.
On the one hand, sixty years ago, SFL Theory did not exist. Halliday (1961) outlined Halliday's first theory, Scale & Category Grammar, and did not include any discussion of types of structure, though Halliday (1965) did introduce the distinction between multivariate and univariate structures, focusing on the latter. The first statement on structure types varying according to metafunction was Modes of meaning and modes of expression: types of grammatical structure and their determination by different semantic functions (Halliday 1979). An earlier paper on structure, Language structure and language function (Halliday 1970) did not propose such a structure typology.

[3] Halliday (1979) On Structure Types
In English, experiential options tend to generate constituent-like structures, actually constellations of elements such as can be fairly easily represented in constituency terms. Interpersonal options generate prosodic structures, extending over long stretches (for example intonation contours), which are much less constituent-like. Textual options generate culminative structures, elements occurring at the boundaries of significant units, and give a kind of periodicity to the text, which is part of what we recognise as “texture”. Logical options generate recursive structures, paratactic and hypotactic, which differ from all the other three in that they generate complexes — clause complex, group complex, word complex – and not simple units.

[1] The Grammar Of Algebraic Mathematics
Blogger Comments:
To be clear, what Doran refers to as the 'radically iterative grammar' of algebra is simply the fact that solving an algebraic equation involves the paratactic elaboration of that equation. This is not problematical from the perspective of SFL Theory.
Experientially, an algebraic equation is a decoding identifying clause. Solving the equation involves elaborating it until each unknown Token is identified by a Value.
