Not easy to describe realisation and instantiation together in a gotcha friendly soundbite...Genre configures recurrent dynamic couplings of selections in field, tenor, mode systems. Cultures assign names to these recurrent configurations ...story, conversation, argument, ceremony... SFL names them as features in system networks. Named features generalise recurrent instances. Features in field, tenor, mode systems are of a different order...item, activity, property; tender, render..

[1] To be clear, in SFL Theory, the "soundbites" are 'situation' for an instance of context, and 'text' for an instance of the content plane of language.
[2] This confuses stratification with instantiation. On the one hand, in Martin's model of stratified context, where functional varieties of language are misunderstood as the full potential of the culture as a semiotic system, the relation between the strata of genre and register, like any other strata, is simply realisation: the stratum of genre (e.g. narrative) is construed as realised by the stratum of register (e.g. the tenor relations between speakers and addressees).
On the other hand, "recurrent dynamic couplings of selections" describes the vector of instantiation ('dynamic couplings of selections') at the level of instance type ('recurrent').
