What is NOT part of a Mule 3 message?

Explanation:
In Mule 3, a message carries the actual data being processed and its related metadata. The payload is the main content of the message, attributes hold metadata about the message (such as transport and routing information), and attachments are extra binary or text pieces that travel with the message. Variables, however, are not embedded in the message itself; they live in the flow’s variable scope and are used to store and share data within a flow during processing. You’d access them with the MEL expression for flow variables (for example, vars.myVar). So the thing that is not part of a Mule 3 message is the variables.
