An application is using Messaging to receive Messages.
How can a messaging receiver gracefully handle receiving a message that makes no sense?
The receiver should move the improper message to an Invalid Message Channel, a special channel for messages that could not be processed by their receivers.
When designing a messaging system for applications to use, the administrator will need to define one or more Invalid Message Channels for the applications to use.
The Invalid Message Channel will not be used for normal, successful communication, so its being cluttered with improper messages will not cause a problem. An error handler that wants to diagnose improper messages can use a receiver on the invalid channel to detect messages as they become available.
