I think so far that the annotation solution is good and we should keep it.
When looking at the discussion I believe that there are two issues:

a.1) Should the Horde capability be kept to add a description for a folder?
   a.2) If so, how? With annotations there would be the question: Which one?
        It would only be one annotation, so this is no problem to configure
	   Cyrus to allow it.

I think a.1) should first be decided, 
the discussion was started on kolab-devel.
I still maintain that it is not necessary and should be disabled in the Kolab 
Horde driver for consistency reasons with other clients and lack of 
additional value.

b) How many variety do we need with annotation names for Toltec?
Joon, I did so far not realize that you need to be free to change the 
annotation-name itself. I believe that we can develop a method that can
be implemented in Cyrus that allows for subtypes to be choosen.
It just would be a bit more complicated in the implementation,
as it would need to take a limit into account. It should be no problem
to always keep patches around that losen this limit for now.
So there is no reason to chance the client implementations.
Joon: Can you give us an example of a list of annotations that _could_ 
sometimes be created for a folder?
