My other point is that the analyst works at a different level of abstraction than WS-Policy. How is he to express security or QoS intentions, when the WS-Policy framework provides only highly detailed statements about the implementation? The analyst should be able to indicate that a particular message needs to be, say, tamper-proof, without having to make the very detailed choices that WS-SecurityPolicy requires. While the process of converting intentions to implementation details may indeed be performed by a clever tool set, the intention is lost when looking at the resulting BPEL and WSDL documents. To facilitate portability, reuse, and even composability, it is important that those intentions be captured. Unless, of course, the world settles on just one such clever tool set.... -Ron |
