Fontaine (2017: 4-5):
Context itself is not ‘out there’ as in outside the speaker. While it might be considered to be outside the language system, it cannot be denied that whatever context is, it is connected to or can interact with the language system. Halliday (1991:281) explains the connection as follows:
How do you set about “creating” a context for language? You cannot do it by means of legislation, like decreeing that poems are to be written in praise of a national leader. The only way is for the text itself to create its own context of situation.
This suggests that textual, i.e. linguistic, features are meaningful and that context of situation is effectively the collection of instances of text. Halliday (1991:277) sees this context as “a theoretical construct for explaining how a text relates to the social processes within which it is located”. It is well established in SFL literature that this construct involves three variables or components, commonly termed Field, Tenor and Mode of Discourse, respectively as “the underlying social activity, the persons or “voices” involved in that activity, and the particular functions accorded to the text within it” (ibid.).

[1] To be clear, context does not "interact" with language, because they are distinct levels of symbolic abstraction, not modules at the same level of abstraction. The "connection" between context and language is thus the relation between levels of symbolic abstraction: realisation.
[2] To be clear, the Halliday quote relates an instance of language (text) to an instance of context (situation). The point is that, because language realises context, an instance of language "creates" an instance of context.
[3] To be clear, the Halliday quote does not suggest that the linguistic features instantiated as text are meaningful; see [2] above. Since SFL Theory models language as meaning potential, this is a given.
[4] To be clear, the Halliday quote does not suggest that an instance of context (situation) is "the collection of instances of text"; see [2] above. On the one hand, the relation between context and language is realisation (elaborating identification), not composition (extending identification or ascription); see Halliday & Matthiessen (1999: 145-6). On the other hand, the wording "instances of text" misunderstands instantiation, according to which a text is an instance of language.
