admin.appserverSetPort( config as element(configuration), appserver-id as (Number|String), value as Number ) as element(configuration)
		  This function changes the port in the configuration for
		  the specified App Server to the specified number.  Changing
		  the port is a "cold" operation; when you use
	      
	      admin.saveConfiguration to save the
		  configuration, it will automatically restart
		  MarkLogic Server.
