[turba] lists, vcard 3.0 and turba

[Pierluigi Ruffo]

Hi,

I'm trying to use cardbook or sogo-connector on thunderbird to 
sincronize addressbook with turba (on horde).
I realized I had to use vcard 3.0 which does not support lists.
To take advantage of the lists, however, I would use the 
X-ADDRESSBOOKSERVER-MEMBER and X-ADDRESSBOOKSERVER-KIND fields.

Please, could you tell me a guide or an example to implement this 
feature in turba? I searched a lot on the internet but I have not find a 
guide

Thanks a lot.

   Pierluigi
