Sorry, for my late answer. I had no Internet access this weekend, 
reinstalled my private computer ;-)

That's what we are doing! Our com::sun::star::uno::XInterface looks 
almost identical to BONOBOs Unknown. 

The only point is, the service specifies WHICH interfaces are mandatory 
and which are optional for a certain purpose. Additionally it's possible 
to create objects using the service name, yes, that is like a stored 
BONOBO query.
