/**
* The container for the SOAPHeader and SOAPBody portions of a
* <code>SOAPPart</code> object. By default, a <code>SOAPMessage</code>
* object is created with a <code>SOAPPart</code> object that has a
* <code>SOAPEnvelope</code> object. The <code>SOAPEnvelope</code> object
* by default has an empty <code>SOAPBody</code> object and an empty
* <code>SOAPHeader</code> object. The <code>SOAPBody</code> object is
* required, and the <code>SOAPHeader</code> object, though
* optional, is used in the majority of cases. If the
* <code>SOAPHeader</code> object is not needed, it can be deleted,
* which is shown later.
* <P>
* A client can access the <code>SOAPHeader</code> and <code>SOAPBody</code>
* objects by calling the methods <code>SOAPEnvelope.getHeader</code> and
* <code>SOAPEnvelope.getBody</code>. The
* following lines of code use these two methods after starting with
* the <code>SOAPMessage</code>
* object <i>message</i> to get the <code>SOAPPart</code> object <i>sp</i>,
* which is then used to get the <code>SOAPEnvelope</code> object <i>se</i>.
*
* <PRE>
* SOAPPart sp = message.getSOAPPart();
* SOAPEnvelope se = sp.getEnvelope();
* SOAPHeader sh = se.getHeader();
* SOAPBody sb = se.getBody();
* </PRE>
* <P>
* It is possible to change the body or header of a <code>SOAPEnvelope</code>
* object by retrieving the current one, deleting it, and then adding
* a new body or header. The <code>javax.xml.soap.Node</code> method
* <code>deleteNode</code> deletes the XML element (node) on which it is
* called. For example, the following line of code deletes the
* <code>SOAPBody</code> object that is retrieved by the method <code>getBody</code>.
* <PRE>
* se.getBody().detachNode();
* </PRE>
* To create a <code>SOAPHeader</code> object to replace the one that was removed,
* a client uses
* the method <code>SOAPEnvelope.addHeader</code>, which creates a new header and
* adds it to the <code>SOAPEnvelope</code> object. Similarly, the method
* <code>addBody</code> creates a new <code>SOAPBody</code> object and adds
* it to the <code>SOAPEnvelope</code> object. The following code fragment
* retrieves the current header, removes it, and adds a new one. Then
* it retrieves the current body, removes it, and adds a new one.
*
* <PRE>
* SOAPPart sp = message.getSOAPPart();
* SOAPEnvelope se = sp.getEnvelope();
* se.getHeader().detachNode();
* SOAPHeader sh = se.addHeader();
* se.getBody().detachNode();
* SOAPBody sb = se.addBody();
* </PRE>
* It is an error to add a <code>SOAPBody</code> or <code>SOAPHeader</code>
* object if one already exists.
* <P>
* The <code>SOAPEnvelope</code> interface provides three methods for creating
* <code>Name</code> objects. One method creates <code>Name</code> objects with
* a local name, a namespace prefix, and a namesapce URI. The second method creates
* <code>Name</code> objects with a local name and a namespace prefix, and the third
* creates <code>Name</code> objects with just a local name. The following line of
* code, in which <i>se</i> is a <code>SOAPEnvelope</code> object, creates a new
* <code>Name</code> object with all three.
* <PRE>
* Name name = se.createName("GetLastTradePrice", "WOMBAT",
* "http://www.wombat.org/trader");
* </PRE>
