That's why I assumed the spec should say
both "MUST send as zero" and "MUST ignore upon receipt",
It would be nice in general if it were understood
that that is the required behavior in fields marked as "RESERVED".
(That way specs wouldn't have to say "MUST send as zero" and "MUST ignore
on receipt" for every reserved field, it would just be assumed
by calling the field "reserved").

I assume we're not arguing over the desired behavior...just the wording.
