+Camel can supply exchange information as variables when applying a JSLT
expression on the body. The available variables from the *Exchange* are:
+[width="100%",cols="2,5",options="header"]

+| name | value
+| headers | The headers of the In message as a json object
+| exchange.properties | The *Exchange* properties as a json object. _exchange_
is the name of the variable and _properties_ is the path to the exchange
properties. Available if _allowContextMapAll_ option is true.

+
+All the values that cannot be converted to json with Jackson are denied and
will not be available in the jslt expression.

+For example, the header named "type" and the exchange property "instance" can
be accessed like
