Axis is the systemic in systemic functional. In this theory, the coupling of generalisation with abstraction in the axial relation is the basis of semiosis. It is not merely a formalism of the theory, rather the formalism mirrors the semiotic relation. There can be no structures outside of systems, and no systems without structures. This includes systems at each rank, stratum and metafunction, of denotative semiotics like language and image, and connotative semiotics like register and genre.There are plenty of other theories out there, but axis is what sets this one apart. SFS has been influenced by many theories in lx and other disciplines. It proceeds by examining the objects of these theories through the lens of axis, with procedures designed by Halliday in the 1960s for phonology and grammar, and applied since to these and other strata and modalities.

[1] This is misleading, because it is untrue. Axis is a dimension with two orders: paradigmatic and syntagmatic. The 'systemic' in 'systemic functional' is the paradigmatic order of axis only.
[2] This is misleading, because it is untrue. The axial relation is the (realisation) relation between the paradigmatic axis and the syntagmatic axis. It is not a "coupling of generalisation with abstraction".
[3] This is misleading, because it is untrue. Structures are, by definition, "outside of systems" since the two are of different orders: structures are syntagmatic (chains), whereas systems are paradigmatic (choices).
[4] This is misleading, because it is untrue. Hjelmslev's connotative semiotic is a semiotic that has a denotative semiotic as its expression plane. What Rose refers to as a connotative semiotic is only the content plane of the connotative semiotic. However, register and genre (text type) are varieties of a denotative semiotic: language. In terms of a connotative semiotic, register and genre are on its expression plane (language) not its content plane (context).
[5] This is misleading, because it is untrue. There was no Systemic Functional theory in the 1960s. Halliday's theory at that time was Scale-&-Category Grammar, which had no system networks and no metafunctions.
