I would first modify the target namespaces on the schemas so there are no conflicts with having multiple schemas with the same root node. Then i would use a listen shape with multiple recieve shapes. The listen shape would allow for the orchestration to listen for different messages matching a schema for any of the recieve shapes in the listen shape. However, you need to change the namespaces for the schemas…
1. Open a project that has the schema
2. Double-click the schema to open it
3. Select the schema node.
4. Right-click and select properties
5. Modify the target namespace property.
