I have some questions that I forgot to add to the mail:
1. Is it necessary to use the two classes AtkRegistry and AtkObjectFactory 
when bridging to ATK or is it possible to create the AtkObjects in an other 
way? The use of these two classes is extremely difficult if your widgets are 
_not_ glib-based.
2. Why is there an AtkDocument within ATK but no Document interface within 
AT-SPI? How do the AT-clients get the access to the DOM?
3. The documentation of AtkDocument does only say that it's possible to 
enquire a gpointer to the DOM. Therefore I suppose we need to convert a 
Qt-based DOM tree to a glib-based DOM tree. Is that correct?
4. The same for AtkStreamableContent: I assume a Qt application that bridges 
to Atk would need to convert a Qt based stream into a Glib based stream. Is 
that correct?
5. I know that AT-SPI is dependend on any Corba-implementation and that ATK is 
dependend on glib. What are the exact dependencies of the library that 
bridges between these two?
