I don't understand this. 

Assuming that this separation does happen.

How do you deal with this problem in your current version of the Toltec 
connector?

I will try to explain it with a realistic use-case:

1. Alice enters a weekly recurring event with attendees in the calendar of her 
boss Bob using OL/Toltec Connector.

2. This event is synchronized to the Kolab server using the old XML format.

3. Bob, who happens to be a KDE Kontact user is reading/synchronizing his 
calendar folder.

4. Alice then changes one attendee for the third occurance in Outlook. (To my 
knowledge Toltec Connector does not prevent the user from doing this and this 
operation is offered by the Outlook GUI to the user)

5. From an Outlook and Alice's end users point of view the operation (changing 
an attendee) was perfectly legal and successful. After all this change is 
reflected correctly in the user interface.

6. According to your observations the newly created exception is now separated 
("creates a new object") from the original recurring event.

7. Then Toltec Connector tries to synchronize the modified event including its 
recurrance rules and its newly introduced exception date to the server

Q1: How does the Toltec Connector deal with this situation today? 

Q2: How is step 4 expressed in the generated XML using todays Kolab XML 
Format?

Q3: What will KDE Kontact see after step 7?

Q4: In which respect is the old format superior to the new proposal?

How does the new format break interoperability? 

(I claim that assuming your observations are correct that the interoperability 
was already broken before!)
