-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Wonderful perennial topic. :) As I always say when this comes up, when writing drafts I've settled on using the 2119 keywords only in their uppercase form, and otherwise using "need to", "ought to", "might" (etc.) to avoid all possible confusion. Sure, it's a bit stilted, but we're not writing gorgeous prose here, we're writing technical specifications that need to be completely clear.
