| /** |
| * 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. |
| * <P> |
| * A <code>SOAPMessage</code> object consists of a SOAP part and optionally |
| * one or more attachment parts. The SOAP part for a <code>SOAPMessage</code> |
| * object is a <code>SOAPPart</code> 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. |
| * <P> |
| * A new <code>SOAPMessage</code> object contains the following by default: |
| * <UL> |
| * <LI>A <code>SOAPPart</code> object |
| * <LI>A <code>SOAPEnvelope</code> object |
| * <LI>A <code>SOAPBody</code> object |
| * <LI>A <code>SOAPHeader</code> object |
| * </UL> |
| * The SOAP part of a message can be retrieved by calling the method <code>SOAPMessage.getSOAPPart()</code>. |
| * The <code>SOAPEnvelope</code> object is retrieved from the <code>SOAPPart</code> |
| * object, and the <code>SOAPEnvelope</code> object is used to retrieve the |
| * <code>SOAPBody</code> and <code>SOAPHeader</code> objects. |
| * |
| * <PRE> |
| * SOAPPart sp = message.getSOAPPart(); |
| * SOAPEnvelope se = sp.getEnvelope(); |
| * SOAPBody sb = se.getBody(); |
| * SOAPHeader sh = se.getHeader(); |
| * </PRE> |
| * |
| * <P> |
| * In addition to the mandatory <code>SOAPPart</code> object, a <code>SOAPMessage</code> |
| * object may contain zero or more <code>AttachmentPart</code> objects, each |
| * of which contains application-specific data. The <code>SOAPMessage</code> |
| * interface provides methods for creating <code>AttachmentPart</code> |
| * objects and also for adding them to a <code>SOAPMessage</code> object. A |
| * party that has received a <code>SOAPMessage</code> object can examine its |
| * contents by retrieving individual attachment parts. |
| * <P> |
| * 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 |
| * <code>AttachmentPart</code> object. |
| * <P> |
| * A <code>MessageFactory</code> object may create <code>SOAPMessage</code> |
| * objects with behavior that is specialized to a particular implementation or |
| * application of SAAJ. For instance, a <code>MessageFactory</code> object |
| * may produce <code>SOAPMessage</code> objects that conform to a particular |
| * Profile such as ebXML. In this case a <code>MessageFactory</code> object |
| * might produce <code>SOAPMessage</code> objects that are initialized with |
| * ebXML headers. |
| * <P> |
| * In order to ensure backward source compatibility, methods that are added to |
| * this class after version 1.1 of the SAAJ specification are all concrete |
| * instead of abstract and they all have default implementations. Unless |
| * otherwise noted in the JavaDocs for those methods the default |
| * implementations simply throw an <code>UnsupportedOperationException</code> |
| * and the SAAJ implementation code must override them with methods that |
| * provide the specified behavior. Legacy client code does not have this |
| * restriction, however, so long as there is no claim made that it conforms to |
| * some later version of the specification than it was originally written for. |
| * A legacy class that extends the SOAPMessage class can be compiled and/or run |
| * against succeeding versions of the SAAJ API without modification. If such a |
| * class was correctly implemented then it will continue to behave correctly |
| * relative to the version of the specification against which it was written. |
