* <p>
* The native version is that used throughout the stack, were the
* WS-A types are represented via the JAXB generated types for the
* 2005/08 schema.
* <p>
* The exposed version is that used when the WS-A types are
* externalized, i.e. are encoded in the headers of outgoing
* messages. For outgoing requests, the exposed version is
* determined from configuration. For outgoing responses, the
* exposed version is determined by the exposed version of
* the corresponding request.
* <p>
* The motivation for using different native and exposed types
* is usually to facilitate a WS-* standard based on an earlier
* version of WS-Adressing (for example WS-RM depends on the
* 2004/08 version).
