Predicative noun phrases occur without a copula in present tense. They do combine with the marker bin in past tense, but despite its origin in English been this is regarded as a TAM auxiliary, not a copula, here.
According to Sandefur (1979: 123), the copula bi occurs in the future tense, but examples of this type are not attested in any other available data. (Cf. also Hudson 1985: 90, who however regards bi as an acrolectal feature). Disregarding this claim, Value 2 has been chosen (and one of Sandefur's examples included).
