Patent ID: 7987253

Claim:
A method for determining an applicable policy for an incoming message comprising a service-level addressing element, said method comprising: using a processor device configured to perform steps of: a) providing a definition for an initial part of a transformation; b) applying a potentially applicable policy to the incoming message to make the service-level addressing element of the incoming message accessible, wherein the service-level addressing element is deemed accessible when it shows a valid syntax upon transformation such that the incoming message, after transformation, comprises any syntactically correct service-level addressing element, wherein the step of applying comprises: applying the initial part of the transformation to the incoming message, which initial part of the transformation is prescribed by said potentially applicable policy; c) selecting the currently applied policy as the applicable policy when the service-level addressing element of the incoming message becomes accessible only to an extent that the service-level addressing element of the incoming message becomes accessible; and d) repeating steps b) and c) with a further potentially applicable policy when the service-level addressing element is not accessible.
