RE: I-D ACTION:draft-dusseault-caldav-00.txt

The Exchange 2000 support for calendaring via WebDAV includes also
some custom features, some proprietary features, etc.  For example,
it does not support the standard ACL model (currently in IESG review)
for WebDAV.  The problem would not be to extend the E2K model but
to subset it, and as such, it is probably not possible to make it 
out-of-the-box compatible.

I don't know if it would be possible to specify a Exchange 2000 
compatible standard.  There could be IPR issues, there could be 
information which isn't available to clients not in a Exchange 
security domain.  Somebody at Microsoft would be able to answer 
these questions.

OTOH, the model isn't really all that different.  The basic proposal
is to represent calendars as WebDAV collections, and to represent calendar 
events as WebDAV resources with a flat list of properties.  Further, the
properties roughly reflect iCalendar semantics.  This is not 
incompatible with the way Exchange 2000 does it.
