RFC 2119 defines a standard set of key words for describing
requirements of a specification.  Many IETF documents have found that
these words cannot accurately capture the nuanced requirements of
their specification.  This document defines additional key words that
can be used to address alternative requirements scenarios.  Authors
who follow these guidelines should incorporate this phrase near the
beginning of their document:

The key words "MUST (BUT WE KNOW YOU WON'T)", "SHOULD CONSIDER",
"REALLY SHOULD NOT", "OUGHT TO", "WOULD PROBABLY", "MAY WISH TO",
"COULD", "POSSIBLE", and "MIGHT" in this document are to be
interpreted as described in RFC 6919.
