Peter said: "Aha, I see the source of confusion. I think the first sentence of Section 5.1 is better written as follows: When the connecting application is an interactive client, construction of the reference identifier SHOULD be based on the source domain and service type provided by a human user (e.g. when specifying the server portion of the user's account name on the server or when explicitly configuring the client to connect to a particular host or URI as in [SIP-LOC]) and SHOULD NOT be based on a target domain derived from the user inputs in an automated fashion (e.g., a host name or domain name discovered through DNS resolution of the source domain). We want to make sure that the reference identifier is based on the source (user-provided) domain, not the target (automatically-derived) domain, except perhaps in several well-defined and carefully-limited scenarios. Peter" [BA] IMHO, this text is much clearer.
