Table 87. Set Out Header Properties
| Name | Description |
|---|---|
| Language | Specifies the expression language used to process the expression. |
| Header Name | Specifies the name of the header. |
| Description | Specifies a text description for the node. This description is included in the generated XML file, but it is informational only. It is not used by Apache Camel. |
| Id | Specifies a unique identifier for the endpoint. The tooling automatically generates an id for a node when it is created, but you can remove that id or replace it with your own. The Camel debugger requires all nodes with a breakpoint set to have a unique id. You can use the id to refer to endpoints in your Camel XML file. |
