This ticket seems to be a small clarification, and I would say it falls within the bounds for very small changes as the chapter is finalized.  Also, we all have to vote on this, so I am ok with including this in this round of changes.  I know this can be a slippery slope, because small is undefined.

This was added as part of the contract to pull all non-controversial
things from MPI-2.2 into the NBC chapter. See Section 5.12.9 in the
draft document.

However, we have one more open thing that is not covered by this
contract. This is captured in ticket #223 and I would like to include it
in the draft asap, however, the Forum decides how to proceed with it.
