[ietf-calsify] Group Event

Hi folks,

I am not sure if my case is feasible but I am trying to write a
backend program that send out message to "A", "B", "C" and "D" and
make "A" as the organizer/chair of a group event and the others as the
attendees.

I have read the "4.2. Group Event Examples" in
http://ri-cal.rubyforge.org/rdoc/docs/draft-ietf-calsify-2446bis-08_t...<http://www.google.com/url?sa=D&q=http://ri-cal.rubyforge.org/rdoc/docs/draft-ietf-calsify-2446bis-08_txt.html&usg=AFQjCNFWpeP5B-MY1RN1dfc_zgckME45Pg>

but it doesn't mention much about what message content should be
constructed for message sending to "A"

Can somebody shed some light on this? In particular, which parameter
(s) should I pay special attention to? Or there is no feasible
solution for my case?

Thanks!
