Yaakov,

Lower case "must" is fine for stating an assumption, and I would suggest
doing so.

Ok, this seems fine for stating requirements.  When changing the document
to Informational, I suggest adding a sentence or two to Section 1 to 
expand on its title - in essence these keywords are being used to state
protocol design requirements, not protocol implementation/behavior requirements.

Thanks,
