Teemu, I think that the spirit of what you propose is correct, but as Keith points out it really isn't appropriate to use RFC 2119 language about a pragmatic approach that clearly lies outside the definition of the DNS namespace. If an implementor is willing to take the risk of transforming www.ex

Now that more people are involved in discussions, this bare name / DNS search list area seems to look like quite a deep swamp without clear IETF consensus. Perhaps we should discuss first if this particular topic (=section 4.6) is needed in this document at all, because, after all, the focus is on

I think we can skirt this rat-hole if we separate the two following distinct cases: Case A: "foo" Case B: "foo." (with terminating "dot"). Case B meets the technical requirements of a Fully Qualified Domain Name, structurally speaking. Case A does not. Case A is a "bare name", case B is not. If
