[XCON] (no subject)

I have a question reguarding Conference Information Data Model for
Centralized Conferencing (XCON)draft-ietf-xcon-common-data-model-13.txt
Internet-Draft.  Section 8.2 talks a little bit about confidentiality.  Is
the intent of this section to allow (say any two) members of a certain
confererance to maintain a private discussion in which the other members
of the same conference would not be privy to?  If so would the
participants interested (or allowed) to join to prvate conversation be
required to reauthenticate, and renegotiate encryption?  Also if this
capability were implemented, would there be in upper limit to number of
private conversations allowed in the conferance, or a limited of the
amount of nesting (e.g. private converstaions within private conversations
with ...)that would be possible?

Thank you,
