A meeting request has all the components of a meeting plus three additional
components to specify the latest dates and time at which the meeting can be
scheduled. A meeting request is used to specify a range of possible meeting
times, to allow scheduling alternatives to be considered. In the meeting
request, the inherited fields for startDate, endDate, and time are used for
the earliest dates and time at which the meeting can be held, i.e., for the
beginning values of each range. The description of the ScheduleMeeting
operation has further details on how meeting requests are handled.
This object is derived from Section 2.4.1 of the Milestone 6 requirements,
