In my opinion, MSH is quite detachable in the picture of BPSS/BPML/BSI. It
can be viewed as an "executor" of the agreed CPA. Of course, the parameters
agreed in CPA should be passed to the MSH for execution. Other than that, I
will regard MSH and BP* to be lived in two separate layers.

Please correct me if my concept is wrong. Thanks.
