I understand what you're asking, and why, but I don't know if it's within my wordsmithing capabilities.  If I changed the RFC2119 normative keywords to regular English words I think that would make the problem go away; would the resulting text be enough for security considerations?

The "MUST research" paragraph comes almost verbatim from RFC3986, Section 7.5, but that says "should" instead of "MUST" -- I'd be happy to move back in that direction here.

Cheers
