I believe that a request-response operation can be either synchronous or asynchronous. The author of the IBM series of articles on asynchronous Web services messages seems to have the same belief. Look at [1] (part 2 of the series), Pattern 2, Request/reply operations, where he says: "In this pattern, request and response are two messages defined within a single request/reply operation and sent as two separate and unrelated transport-level transmissions."
