Good catch - MPI_COMM_SPLIT_TYPE clearly belongs in this list.

This at first feels a little strange, since globally you end up with multiple communicators after the call.  However, each process should end up belonging to at most one new comm, so the info would naturally apply to the comm the process belongs to.
