Martin (1992: 581-2):
As noted with respect to text [7:5] above, variable realisation implies in a sense that all texts are multi-voiced. There is in other words a certain tension in the system, which manifests itself in semiotic processes.
 This involves two dimensions of confusion, as previously identified here. Martin claimed that, because one mother's coding orientation was variably realised linguistically, she had 'more than one voice' in the conversation, and this was falsely equated with being dialogic in the Bakhtinian sense.
 There are two additional dimensions of confusion here — variability with tension, and language with context — since variability in the language realising context (one coding orientation) is misconstrued as tension in the context itself (misconstrued as ideology).
