Martin (1996) characterises metafunctional structures as follows:
However, Martin's structural distinction between experiential and logical meaning actually construes the distinction between unequal status (of nucleus vs satellite) and equal status (of multiple nuclei). That is, Martin's structure typology misconstrues the metafunctional distinction between experiential and logical as the logical distinction between hypotaxis and parataxis. If using Martin's model has led to confusion, this is one possible reason.
