The only reservation I have about this is that it is not specific to Horde and any application that also uses the "/comment" can destroy your values. Now as this is not format specific, this should not be a big issue for Horde.

As this is relate to all Kolab clients, maybe define it under "/vendor/kolab/folder-description"?
