At the transport level, message headers can be translated to context data and
contexts can be translated to message headers. Context interceptors define how
the headers are set to/from contexts and which contexts are affected.
Interceptors are Java classes that implement the following interface. They can
be registered either globally in ode's property configuration file or per
process in the `deploy.xml`.

In addition to static propagation rules, context propagation can be explicitly
configured for outbound interaction activities (i.e. `<invoke>` and `<reply>`.
Therefore, we introduce a new BPEL extension element `<ctx:propagate>` in the
`[http://ode.apache.org/contextPropagation](http://ode.apache.org/contextPropagation)`
namespace (to which the `ctx`\-prefix is bound to), following the syntax as
described below:
