/**
* This class is responsible for transforming between the native WS-Addressing schema version (i.e. 2005/08)
* and exposed version (currently may be 2005/08 or 2004/08).
*
* 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.
*
* 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.
*
* 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).
