This can be done, of course. I only dislike using too many attributes.
Where would, e.g., Argument/Description go? Not as an attribute I hope,
that would be ugly.

Good idea, I'll look into this.

CDIS should not provide service descriptions, only interface description
a service should implement. Maybe the name "Service" is bad, it caused
some troubles on the DBUS mailing list too. I'll change it to
"DesktopInterface" or so? Although I don't really like that name, but
well.

I'll check if this is allowed now, it shouldn't be of course :-) An
argument can only have one type (otherwise dbus_message_get_blah (forget
function name) won't work correctly.

I made a little mistake here: Arguments are given to a method:
	int test (char *test)
			^^^^ Argument
whilst ReturnValues are the returned values (DBUS can return multiple
values AFAIK)
Which means my definition of an Event is bad: an event only returns
values, it doesnt take any arguments.

I dont have any files on fdo ;)
I though Schemalocation was like this: "namespace
location-of-schema-file", as it is now.
