The one in Section 3.1.1.5 seems perfectly fine: it says that the server SHOULD do something, and that if the server has not done that the client MAY do something to try to compensate. A-OK to me. The tricky bits with SHOULD+MAY occur when both key words apply to the same entity under the same conditions. That's not the case here. Barry
