In one embodiment of a computing system, a client supplied binding is received from a client, wherein the client supplied binding includes an XQuery or a script. A predefined binding is stored in a server, wherein said predefined binding includes an XQuery, a script, or a program, allowing the client to select the predefined binding. An exchange receives an Extensible Markup Language (XML) message from a publisher application and sends the XML message to each message queue whose binding matches the XML message.
