First of all, objects do not register. At least, not if you look into the 
protocol itself.

Applications (connections) register. They register "bus names", or more 
simply "names".

However, bindings have borrows the concept of "registering" to objects. In 
bindings, you register an object so that it is available under a given 
object path over D-Bus. But mind you, the action of registering an object 
in a binding carries out absolutely no action at the protocol level: 
neither the bus daemon nor other programs get to know what happens.

Now, you did not mention any binding in your original email or your new 
one. But given that you're so lost, yet your objects seem to be 
introspectable, you are probably using a binding. Which one, you have to 
tell us.

In any case, a binding's job is to provide many of the facilities required 
to interoperate properly with other D-Bus clients. One of such tasks is 
to reply to Introspect requests with the proper XML, generated from the 
object's actual content.
