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.
On the other hand, a range of subtypes has not been proposed for any of the structure types. That is, a range of subtypes has not been proposed for culminative (textual), prosodic (interpersonal), segmental (experiential) or iterative (logical) structures. The relations in iterative structures have always been limited to either hypotactic or paratactic, and both relations may obtain within the same structure.
