That's not obviously stable enough to be cited as a normative reference,
and you have to be sure to match the cases and terms used in that document
perfectly with the cases and terms in the spec, so there's no ambiguity
about how the equations and variables apply to the filters in the spec. The
easiest way to fix those issues is to copy the equations into the spec and
define their variables in terms of entities defined in the spec.

“You have heard that it was said, ‘Love your neighbor and hate your enemy.’
But I tell you, love your enemies and pray for those who persecute you,
that you may be children of your Father in heaven. ... If you love those
who love you, what reward will you get? Are not even the tax collectors
doing that? And if you greet only your own people, what are you doing more
than others?" [Matthew 5:43-47]
