This is likely all documented.  However, it's a
bit tricky to absorb, and perhaps to explain.

Consider taking another look at the doc for this,
and see if you think you could improve it to make
this a bit clearer.

(Just a suggestion.  Pretty much any text can be
improved, and rereading is the way to begin.)
