SOAPFactory is a factory for creating various objects
* that exist in the SOAP XML tree.
* SOAPFactory can be
* used to create XML fragments that will eventually end up in the
* SOAP part. These fragments can be inserted as children of the
* {@link SOAPHeaderElement} or {@link SOAPBodyElement} or
* {@link SOAPEnvelope} or other {@link SOAPElement} objects.
*
* SOAPFactory also has methods to create
* javax.xml.soap.Detail objects as well as
* java.xml.soap.Name objects.
