events and related data structures

Hi,

  <eventhandler statevariable="currentstate">
    <!-- Deal with the incoming call -->
    <transition state="'initial'" event="connection.CONNECTION_ALERTING"
name="evt">
      <assign name="in_callid" expr="evt.callid" />
      <accept callid="in_callid" />
    </transition>

Above is from first sample (calling card sample) in working draft 20021011.
Where does the evt come from? who fills data in that structure? do that
structure vary from event to event? or from implementer to implementer?
Is the member list for such structures defined anywhere in any of the drafts
published?

Is ccxml written for one telephony platform/framework is supposed to work
for some other vendor's platform/framework? say will ccxml created for
"voxeo" work on "telera" and vice versa?

Thanks,
Shridhar
