  Cheng(2021) proposes and characterizes Relative Maximum Likelihood (RML)
updating rule when the ambiguous beliefs are represented by a set of priors.
Relatedly, this note proposes and characterizes Extended RML updating rule when
the ambiguous beliefs are represented by a convex capacity. Two classical
updating rules for convex capacities, Dempster-Shafer (Shafer, 1976) and
Fagin-Halpern rules (Fagin and Halpern, 1990) are included as special cases of
Extended RML.
