Hi

Since I started on the IETF journey there have been a few occasions
where the intent of a WG has been discussed, my recollection is that in
all these cases people have looked into the charter for guidance. The
charter is IMHO a very strong document and once it is settled it is not
easily challenged. 

Also, common sense (based on earlier discussion and email) does not
always apply if the WG disussion gets heated and we all know that there
are different opinions around this WG :-). For this reason the charter
must state even what can be regarded as basic common sense (like he one
proposed in my earlier email).

Regards
/Ingemar
