I would strongly support "MAY fail" rather than "MUST fail" which I believe is consistent with my previous mail [1]. The reason is both as Noah points out it is impossible to verify but also because it is wrong to enforce a requirement for the receiving party to fail unless we have a correctness problem in our specification. This is not the case here as the semantics of the link is defined by the application and not by us. We should not enforce rules on semantics over which we have no control. >How can an external observer distinguish these two cases? >Either can occur due to conditions known only within the >processing node.
