Hi Phil, We submitted -11 with this NEW text to address your comment: The use of a Transport Converter means that there is no end-to-end transport connection between the client and server. This could potentially create problems in some scenarios such as those discussed in Section 4 of [RFC3135]. Some of these problems may not be applicable, for example, a Transport Converter can inform a client by means of Network Failure (65) or Destination Unreachable (97) error messages (Section 4.2.8) that it encounters a failure problem; the client can react accordingly. An endpoint, or its network administrator, can assess the benefit provided by the Transport Converter service versus the risk. This is one reason why the Transport Converter functionality has to be explicitly requested by an endpoint.
