Re: UDP zero checksums and v4 to v6 translators

 In your previous mail you wrote:

   To take in consideration your (useful) remark, the proposal could be  
   improved by replacing a SHOULD by a MAY:
   - IPv6 hosts MAY accept UDP zero checksums (but of course MUST still  
   send non-zero UDP checksums).
   - v4 to v6 translators MAY either compute UDP checksums when  
   receiving UDP zero checksums OR translate with the zero checksum  
   unchanged.
   
=> if you believe this non-issue still needs a solution in standards
IMHO it is far better to deprecate zero UDP checksums. If you don't
believe just reuse RFC 2765 choice.
