/**
* The root class for all SOAP messages. As transmitted on the "wire", a SOAP message is an XML
* document or a MIME message whose first body part is an XML/SOAP document.
*
* A SOAPMessage object consists of a SOAP part and optionally one or more
* attachment parts. The SOAP part for a SOAPMessage object is a SOAPPart
* object, which contains information used for message routing and identification, and which can
* contain application-specific content. All data in the SOAP Part of a message must be in XML
* format.
*
* A new SOAPMessage object contains the following by default:
*
* - A
SOAPPart object
*
* - A
SOAPEnvelope object
*
* - A
SOAPBody object
*
* - A
SOAPHeader object
The SOAP part of a message can be retrieved by
* calling the method SOAPMessage.getSOAPPart(). The SOAPEnvelope object
* is retrieved from the SOAPPart object, and the SOAPEnvelope object is
* used to retrieve the SOAPBody and SOAPHeader objects. SOAPPart
* sp = message.getSOAPPart(); SOAPEnvelope se = sp.getEnvelope(); SOAPBody sb = se.getBody();
* SOAPHeader sh = se.getHeader();
*
* In addition to the mandatory SOAPPart object, a SOAPMessage object
* may contain zero or more AttachmentPart objects, each of which contains
* application-specific data. The SOAPMessage interface provides methods for creating
* AttachmentPart objects and also for adding them to a SOAPMessage
* object. A party that has received a SOAPMessage object can examine its contents by
* retrieving individual attachment parts.
*
* Unlike the rest of a SOAP message, an attachment is not required to be in XML format and can
* therefore be anything from simple text to an image file. Consequently, any message content that
* is not in XML format must be in an AttachmentPart object.
*
* A MessageFactory object creates new SOAPMessage objects. If the
* MessageFactory object was initialized with a messaging Profile, it produces
* SOAPMessage objects that conform to that Profile. For example, a
* SOAPMessage object created by a MessageFactory object initialized with
* the ebXML Profile will have the appropriate ebXML headers.
