[CalendarServer-dev] Differences between CalendarServer and iCal Server DTD

[Pascal Robert]

I'm building a WebObjects framework to talk to CalDAV and I see that  
both Calendar Server and iCal Server have a XML Namespace for  
extensions.  I found the DTD for Calendar Server here:

http://trac.calendarserver.org/projects/calendarserver/browser/ 
CalendarServer/trunk/twistedcaldav/customxml.py

But iCal Server is using a different namespace and I can't find it :- 
(  I would like to compare the two set of attributes to find  
differences between them (I know that the iCal one have a "calendar- 
color" attribute that Calendar Server doesn't have).
