Also, if the top most production in BNF specyfing field's value is #(values) it does NOT mean the field is safe for merging although this seems to be implied by the statement in the spec starting with "Multiple header fields with the same field name MUST NOT be sent (...)"

I still have very hard time to understand how the statement "MUST NOT be sent " is working, if it seems good to in fact not enforce it. Should it be dropped?
