Shared Faults.

There are several faults like ResourceUnknowFault TopicNotSupportedFault, InvalidTopicExpressionFault
that are defined in multiple namespaces within WSRF itself and Notification interfaces.  More than likely in
most implementation the source of such faults are from a common component. Which means some implementing components
would need to capture the actual exception thrown by the common component and rethrow a new exception that when deserialized
match the namespace for that particular interface in the WSDL.  I would like to ask consider moving at least these shared exceptions to a separate xsd file with its own namespace to make to make them the same across all interfaces.
