Summary:
CalCalendar objects fall into two categories: task calendars, and event calendars.  However, there is no API in CalCalendar (or anywhere else in Calendar Store) which is able to distinguish between the two.  

Steps to Reproduce:
NSArray* calendars = [[CalCalendarStore defaultCalendarStore] calendars];
for( CalCalendar* aCalendar in calendars ) {
    NSLog( @"calendar: %@", aCalendar );
}

Expected Results:
A property or some other mechanism to distinguish between task calendars and event calendars.

Actual Results:
No such property or mechanism exists.  Output from the above code:
calendar: CalCalendar <0x6e04d10> {UID = 8AA8FFAD-D781-47F7-9231-CF66E1753983; title = Work; notes = (null); color = NSCalibratedRGBColorSpace 0.054902 0.380392 0.72549 1; type = CalDAV; editable = 1}
calendar: CalCalendar <0x6e05000> {UID = A7F4A1B2-D1CF-4A20-9F84-CD1A1E99773E; title = Home; notes = ; color = NSCalibratedRGBColorSpace 0.72549 0.054902 0.156863 1; type = CalDAV; editable = 1}

Notes:
Any app that handles events or tasks would need to be able to distinguish between the two types of calendars.  For example, an app might want to display a list of calendars for the user to add an event to.  Without being able to discern between event and task calendars, the app would need to list task calendars along with event calendars; not a good user experience.
