RMark won't allow an mlogit link function for the 2 species occupancy model (original specification).
However, r detection parameters rAb, raB, rAB, rab, need to be constrained to sum to 1. See,

RMark error:
"Error in make.mark.model(data.proc, title = title, parameters = model.parameters, :
Mlogit link not allowed with parameter rAB
Error in mark(dp, ddl, model.parameters = list(PsiAB = PsiAB, PsiA = PsiA, :
Misspecification of model or internal error in code"
