/**
* XMLPart
*
* The XML portion of a Message
*
* The JAX-WS implementation (proxy, message receiver, etc.) interact with the
* Message via Blocks. A Block is represented in the message as a root element tree
* in either the header, body or fault detail section. The Blocks can be easily
* decomposed into business objects (which are needed on the JAX-WS interfaces).
*
* In addition, the JAX-WS handler model requires that the XMLPart be exposed as
* an SAAJ SOAPEnvelope.
*
* The XMLPart abstraction hides the details of the message transformations from
* the JAX-WS implementation.
*
