/**
* 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
* SOAPHeader object.
*
* A SOAPEnvelope object contains an empty
* SOAPHeader object by default. If the
* SOAPHeader object, which is optional, is not needed, it
* can be retrieved and deleted with the following line of code.
* The variable se is a SOAPEnvelope
* object.
*
* se.getHeader().detachNode();
*
* A SOAPHeader object is created with the
* SOAPEnvelope method addHeader. This method,
* which creates a new header and adds it to the envelope, may be
* called only after the existing header has been removed.
*
* se.getHeader().detachNode();
* SOAPHeader sh = se.addHeader();
*
*
* A SOAPHeader object can have only
* SOAPHeaderElement objects as its immediate children. The
* method addHeaderElement creates a new
* HeaderElement object and adds it to the
* SOAPHeader object. In the following line of code, the
* argument to the method addHeaderElement is a
* Name object that is the name for the new
* HeaderElement object.
*
* SOAPHeaderElement shElement = sh.addHeaderElement(name);
*
