The paper presents one additional possibility how to define conditional independence relation for belief functions. The approach is based on the operator of composition originally designed for multidimensional model processing. Not to make confusion with the preceding definitions we call this relation /emph{conditional irrelevance}. The main result of the paper, Block Irrelevance theorem, shows that this relation meets the semigraphoid axioms.
