Martin (1992: 280, 281):
Identifying clauses can first be divided into those with an additional agent and those without.. This additional agent may have the function of assigning Token to Value…
Blogger Comment:
To be clear, there is only an additional Agent in an identifying clause if it is both assigned and encoding, and this is only possible in operative voice (Halliday 1994: 165). (In encoding clauses, Token conflates with Agent.) Unassigned decoding clauses are middle: they have no Agent.
The accompanying system network (Fig. 5.4.) misconstrues unassigned vs assigned as single agency vs double agency.
