Fawcett (2010: 27):
A 'univariate' structure, then, is said to be a 'structure' that is composed of two or more categories that are the same. More specifically, the 'taxis' is between two or more classes of unit — predominantly between clauses, but also between groups, words and even morphemes. As we shall see when we meet the concept of 'co-ordination' in Section 11.8.2 of Chapter 11, the Cardiff Grammar models a 'paratactic' relationship between two or more units, as in cats, dogs and horses, as three co-ordinated units that jointly fill an element of structure in a higher unit in the tree. There are a number of problems to consider in relation to co-ordination, but we shall delay the discussion of these to Section 11.8.2 of Chapter 11. We can therefore set aside the concept of 'parataxis' (as we have already done with 'multivariate' structures).

[1] This is misleading. To be clear, a univariate structure is 'an iteration of the same functional relationship' and is 'unique to the logical mode of meaning' (Halliday & Matthiessen 2014: 451).
[2] This is untrue. Tactic relations obtain between units of the same class and rank — e.g. between nominal groups — not between different classes of unit — e.g. not between nominal and verbal groups.
[3] This confuses co-ordination — paratactic extension — with parataxis in general. Parataxis also combines with the other logico-semantic types: elaboration, enhancement and projection. These have not been considered at all in this discussion of parataxis.
[4] This is misleading in what it implies. In SFL theory, not just the Cardiff Grammar, a paratactically extending group complex like cats, dogs and horses serves as an element of structure of a higher unit, the clause. For example, in the clause they have cats, dogs and horses, the nominal group complex serves as the possessed Attribute of clause structure.
