* <P>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 object.
* <p/>
* <P>A SOAPEnvelope object contains an empty SOAPHeader object by
* default. If the <CODE> SOAPHeader object, which is optional, is not needed, it can be
* retrieved and deleted with the following line of code. The variable <I>se is a
* <CODE>SOAPEnvelope object. se.getHeader().detachNode();
A
* <CODE>SOAPHeader object is created with the SOAPEnvelope method
* <CODE>addHeaderBlock. 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.addHeaderBlock(); </PRE>
* <p/>
* <P>A SOAPHeader object can have only SOAPHeaderElement objects as its
* immediate children. The method <CODE>addHeaderElement creates a new
* HeaderElement</CODE> object and adds it to the SOAPHeader object. In the following
* line of code, the argument to the method <CODE>addHeaderElement is a Name
* object that is the name for the new <CODE> HeaderElement object.
* SOAPHeaderElement shElement = sh.addHeaderElement(name); </PRE>
