[CalendarServer-dev] use of X-CALENDARSERVER-ACCESS

I'm new to this list (and CalDAV in general), and apologize if this  
question has been asked before. A search of the 2008 archives came up  

My question is about the use of X-CALENDARSERVER-ACCESS in the Darwin  
Calendar Server. But allow me to start with a little background: I  
wanted to see if iCal can handle private events when the calendar is  
hosted on a CalDAV-compliant server, and I came across this article: http://support.apple.com/kb/TS1694 
, which suggests if the server supports private events, the option  
automatically unlocks in iCal. "Weird," I thought, as I have not seen  
any other Apple apps adapt themselves based on server capability.

But sure enough, after downloading and configuraing darwin calendar,  
the private option appears in iCal. A colleague asked if it uses CLASS  
property as defined in RFC 2445, so I looked at the ics file, and  

After a while I found caldav-privateevents.txt, which details how  
other CalDAV servers can also unlock the private option in iCal, but  
it doesn't explain why X-CALENDARSERVER-ACCESS was chosen over CLASS  
in the first place.

Can someone explain this to me? I'm sure there's a reason.
