Problem with schemas' import when there are multiple xsds in many dirs

The problem appears when the wsdl file, that accompanies the bpel file, imports data types' definitions from multiple referenced xsd files that are located in subdirectories relative to 'root' directory of service unit.
It is impossible to deploy such a service unit to ServiceMix.

In the attachment there is the example of such service unit. Test case is simple, just try to deploy this service and the error messages should be clearly seen in the logs.
