I still have not entirely wrapped my head around _EXTRA, _REF_EXTRA,
and _STRICT_EXTRA despite numerous readings of discussions on this
group about these keywords.

Does anyone have a graphical explanation of these? A flow-chart with
arrows and diamonds and YES/NO keywords perhaps? I have a feeling that
would get the concept across. If not, perhaps I'll take what I do
understand of these keywords and try to create such a chart.
