/**
* A representation of the SOAP header
* element. A SOAP header element consists of XML data that affects
* the way the application-specific content is processed by the message
* provider. For example, transaction semantics, authentication information,
* and so on, can be specified as the content of a <code>SOAPHeader</code>
* object.
* <P>
* A <code>SOAPEnvelope</code> object contains an empty
* <code>SOAPHeader</code> object by default. If the <code>SOAPHeader</code>
* object, which is optional, is not needed, it can be retrieved and deleted
* with the following line of code. The variable <i>se</i> is a
* <code>SOAPEnvelope</code> object.
* <PRE>
* se.getHeader().detachNode();
* </PRE>
*
* A <code>SOAPHeader</code> object is created with the <code>SOAPEnvelope</code>
* method <code>addHeader</code>. This method, which creates a new header and adds it
* to the envelope, may be called only after the existing header has been removed.
*
* <PRE>
* se.getHeader().detachNode();
* SOAPHeader sh = se.addHeader();
* </PRE>
* <P>
* A <code>SOAPHeader</code> object can have only <code>SOAPHeaderElement</code>
* objects as its immediate children. The method <code>addHeaderElement</code>
* creates a new <code>HeaderElement</code> object and adds it to the
* <code>SOAPHeader</code> object. In the following line of code, the
* argument to the method <code>addHeaderElement</code> is a <code>Name</code>
* object that is the name for the new <code>HeaderElement</code> object.
* <PRE>
* SOAPHeaderElement shElement = sh.addHeaderElement(name);
* </PRE>
