/**
* 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.
*
* A {@code SOAPEnvelope} object contains an empty
* {@code 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 se is a
* {@code SOAPEnvelope} object.
*
{@code
* se.getHeader().detachNode();
* }
*
* A {@code SOAPHeader} object is created with the {@code SOAPEnvelope}
* method {@code 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.
*
* {@code
* se.getHeader().detachNode();
* SOAPHeader sh = se.addHeader();
* }
*
* A {@code SOAPHeader} object can have only {@code SOAPHeaderElement}
* objects as its immediate children. The method {@code addHeaderElement}
* creates a new {@code HeaderElement} object and adds it to the
* {@code SOAPHeader} object. In the following line of code, the
* argument to the method {@code addHeaderElement} is a {@code Name}
* object that is the name for the new {@code HeaderElement} object.
*
{@code
* SOAPHeaderElement shElement = sh.addHeaderElement(name);
* }
