/**
 * The container for the SOAP-specific portion of a <code>SOAPMessage
 * object. All messages are required to have a SOAP part, so when a
 * <code>SOAPMessage object is created, it will automatically
 * have a <code>SOAPPart object.
 *<P>
 * A <code>SOAPPart object is a MIME part and has the MIME headers
 * Content-Id, Content-Location, and Content-Type.  Because the value of
 * Content-Type must be "text/xml", a <code>SOAPPart object automatically
 * has a MIME header of Content-Type with its value set to "text/xml".
 * The value must be "text/xml" because content in the SOAP part of a
 * message must be in XML format.  Content that is not of type "text/xml"
 * must be in an <code>AttachmentPart object rather than in the
 * <code>SOAPPart object.
 * <P>
 * When a message is sent, its SOAP part must have the MIME header Content-Type
 * set to "text/xml". Or, from the other perspective, the SOAP part of any
 * message that is received must have the MIME header Content-Type with a
 * value of "text/xml".
 * <P>
 * A client can access the <code>SOAPPart object of a
 * <code>SOAPMessage object by
 * calling the method <code>SOAPMessage.getSOAPPart. The
 * following  line of code, in which <code>message is a
 * <code>SOAPMessage object, retrieves the SOAP part of a message.
 * <PRE>
 *   SOAPPart soapPart = message.getSOAPPart();
 * </PRE>
 * <P>
 * A <code>SOAPPart object contains a SOAPEnvelope object,
 * which in turn contains a <code>SOAPBody object and a
 * <code>SOAPHeader object.
 * The <code>SOAPPart method getEnvelope can be used
 * to retrieve the <code>SOAPEnvelope object.
