+     If there is an event in the local database which is not "public", but "private",

+5) How a filter works
+*************************************************************************
+
+A filter is a rule to decide if a particular item
+(calendar iten item or contact item) belongs to a set of items.
+For example, you can specify a set as:
+Only items, that belongs to that category.
+Or: Only items, that does not belong to that category.
+Or: Only items, that are public.
+
+If you specify a filter in a syncing profile, you can set the
+rules of adding items to the local or remote database.
+
+Example:
+You have a public calendar in your company, which contains all
+company relevant data.
+
+You have different projects in the company and for project specific events
+is always set the project name as a category: 
+E.g. all events of the project PRO_ABC do have set the categorie PRO_ABC.
+But you are not interested in events of PRO_ABC, because you are not working on it.
+Then you can specify a filter: All, but not with categoroy PRO_ABC.
+When you specify this filter as an incoming filter for your sync profile,
+all events of the company are synced and added to your local calendar, but not
+the evenst of the project PRO_ABC.
+
+You do not want that your private data can be seen 
+in the public calendar of your company.
+Well, set the property to "private" for all your private data 
+and specify an outgoing filter: Only " public" and "confidential".
+Then you can sync your personal calendar with the calendar of the company,
+but your private data is not added to the public calendar.
