Routing Rules in a Mediator component carry several attributes that govern the routing rule run time behavior. These include: XSLT or XQuery used for transformation, the filter expression, target operation, the parallel or sequential indicator, the Schematron document used for validation, the native validation and the value assignment (for example for header properties).
In SOA Suite 12c, we can conditionally set overriding values for each of these attributes. That means that at run time, based on the evaluation of some expression against the contents of the request message (or the time of the day, day of the week,…) , we can use a different transformation stylesheet or assign a different header value. This dynamic override of the static rule definition is configured using the Override Using option – shown last in the figure overhead.

Domain Value Maps are still DVMs in SOA Suite 12c. Create them in JDeveloper, use them in Transformations and Assignments in Mediator and BPEL. Inspect them and edit them at run time using SOA Composer. Nothing really new there.
What is new:
- In 12c, we can use XQuery in BPEL and Mediator – and in these XQuery functions we can use Domain Value Map as well.
- In 12c, we can use both XQuery and XSL Map in Service Bus – and here we can use Domain Value Maps as well
- In 12c, we can inspect and edit Domain Value Maps also at runtime in the Service Bus Design Composer/Console
- In 12c, we can create Domain Value Maps in Service Bus projects, publish them to the MDS Design Time Repository as well as import them into Service Bus projects from that repository
So as of now, in SOA Suite 12c we can leverage Domain Value Map from Service Bus components.
