For outgoing messages, <invoke> activities can be configured to take context data from a (different) partner link, pass it again through a <em>context interceptor</em> which translates the data back to transport-specific metadata. Such propagation configuration can be defined per invoke activity in the process model or on a global level in the deployment descriptor.
Context data can be assigned to variables. Therefore, the context data is translated into XML data, following a predefined schema. It is possible to define which contexts of a partner link are copied to a variable. Similarly, context data can be copied from a variable back into the context of a certain partner link.
Contexts can be used to classify or tag process instances and it is useful to make this information accessible for process management tools. Hence, this specification extends the process management API to make context data queryable and accessible.</p>
