The individual statement reference pages already have sections for
standards divergences.  Admittedly, that framework doesn't help for
discrepancies that can't be tied to a statement type ... but I don't
think we should throw in duplicative material of this sort.  It's
tough enough to keep one instance of the info up-to-date.  So I'd
want to see some structure for this that respects that existing
set of information.
