Given that all vendors (large, medium or small) have to deal with existing 
customer bases I dont find this astonishing.  In any case, the 
flags/settings we create need to be comprehensive and clear for all 
parties so that correct behaviour can be determined.

The iTIP fallbacks you refer to are protocol level behaviours like:

Method           Fallback
--------------   -----------------------------------------------------
PUBLISH          Required
REQUEST          PUBLISH
REPLY            Required
ADD              Required
CANCEL           Required
REFRESH          Required
COUNTER          Reply with Not Supported
DECLINECOUNTER   Required if EVENT-COUNTER is implemented; otherwise
                 reply with Not Supported

The issues with EXPAND are not germane to iTIP messaging so its not an 
iTIP issue/problem as you contend.  The questions related to EXPAND are 
related to CAP features/abilities and nothing directly related to iTIP.

iTIP defines the semantics for doing workflow between 2 parties and 
nothing more.  The issues with EXPAND are non-workflow related and thus 
CAP specific; iTIP does not cover accessing and manipulating calendar 
contents like CAP does.

Now can we try to address the questions so CAP is clear and as 
unambiguious as we can make it?
