Roger,

I was thinking about what this might look like in the spec and how other
sections might benefit or need to change.  What this has led me to is to
think more about best practices or guidelines at the moment, perhaps we can
sketch out what a section might look like there and can determine if it is
unnatural there or fits nicely.  It seems like a logical fit in the BP&G.
