Table 113. 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.
