   #each argument name/value pair, adds a child element
   #to it.  It's an error to have an even number of
   #arguments to this function.
   #Example: myserver->invoke('snapshot-create',
   #                                'snapshot', 'mysnapshot',
   #                            'volume', 'vol0');
