/**
 * Tests the use of the WS-Policy Framework to determine the behaviour of the HTTP client
 * by policies including the HTTPClientPolicy assertion attached to different subjects
 * of the contract (endpoint, operation, binding, messager).
 * The server in this test is not policy aware.
 * Neither client nor server do have addressing interceptors installed: there are no addressing
 * assertions that would trigger the installation of the interceptors on the client side. The use
 * of the DecoupledEndpoint attribute in the HTTPClientPolicy assertions is merely for illustrating
 * the use of multiple compatible or incompatible assertions.
