OK, we'll try that;

Hmmmm... OK, I guess you mean, if the user wants to have, eg. FirstName, 
LastName and EmailAdress of a Person, that should be queried in one go 
(as a fragment of the whole document) instead of either loading the 
whole Person OR fetching each datum individually (resulting in 3 XmlRpc
function calls);
OK... I see what you mean... hmmmmm... I guess we should give some
thought to opening our XmlRpc Subsystem to the Programmer a little more
instead of completely hiding it; allowing the Programmer to set the
attributes of a fetch() call would be an idea; I suppose, we here, at 
the JOGI HQ, will need to get our thinking caps out again...

Sparetime... yeah... that word that got kicked out of my vocabulary
some time ago... ;-)

Yup, I see; it's basically like knowing when to use DOM and
when to use SAX when dealing with XML;
