Martin (1992: 455):
The pattern of interaction in [6:23] is outlined below, listing the text's News, hyper-New and macro-New. The News of the introduction are listed (in plain face) but do not participate in this pattern; they participate instead in the complementary function of predicting the text's method of development reviewed above.
To be clear, on this model, information that is presented by the writer as New to the reader in the introduction (Martin's macro-Theme) does not participate in the 'accumulation of New information'.
On the other hand, repeated information, paragraph summary and text summary, is deemed to be new: Martin's hyper-New and macro-New, respectively.
