an Entity references as follows:
A plenary session or plenum is a session of a conference which all members of all parties are to attend. Such a session may include a broad range of content, from keynotes to panel discussions, and is not necessarily related to a specific style of presentation or deliberative process. The term has been used in the teaching profession to describe when information is summarized. This often encourages class participation or networking. When a session is not fully attended, it must have a quorum: the minimum number of members required to continue process (by the group's charter or bylaws).
