33 * The container for the SOAP-specific portion of a <code>SOAPMessage</code>
34 * object. All messages are required to have a SOAP part, so when a
35 * <code>SOAPMessage</code> object is created, it will automatically
36 * have a <code>SOAPPart</code> object.
37 *<P>
38 * A <code>SOAPPart</code> object is a MIME part and has the MIME headers
39 * Content-Id, Content-Location, and Content-Type. Because the value of
40 * Content-Type must be "text/xml", a <code>SOAPPart</code> object automatically
41 * has a MIME header of Content-Type with its value set to "text/xml".
42 * The value must be "text/xml" because content in the SOAP part of a
43 * message must be in XML format. Content that is not of type "text/xml"
44 * must be in an <code>AttachmentPart</code> object rather than in the
45 * <code>SOAPPart</code> object.
46 * <P>
47 * When a message is sent, its SOAP part must have the MIME header Content-Type
48 * set to "text/xml". Or, from the other perspective, the SOAP part of any
49 * message that is received must have the MIME header Content-Type with a
50 * value of "text/xml".
51 * <P>
52 * A client can access the <code>SOAPPart</code> object of a
53 * <code>SOAPMessage</code> object by
54 * calling the method <code>SOAPMessage.getSOAPPart</code>. The
55 * following line of code, in which <code>message</code> is a
56 * <code>SOAPMessage</code> object, retrieves the SOAP part of a message.
57 * <PRE>
58 * SOAPPart soapPart = message.getSOAPPart();
59 * </PRE>
60 * <P>
61 * A <code>SOAPPart</code> object contains a <code>SOAPEnvelope</code> object,
62 * which in turn contains a <code>SOAPBody</code> object and a
63 * <code>SOAPHeader</code> object.
64 * The <code>SOAPPart</code> method <code>getEnvelope</code> can be used
65 * to retrieve the <code>SOAPEnvelope</code> object.
