The 3rd paragraph describing leave will be updated to consider both status properties, and how local systems may have multiple types of leave or hold reasons. Another paragraph will be added to this section to describe how waiting list status(es) coud be added to the subjectStatus for local usage. Note: There is no change to the statusHistory elements at this stage, however this will be revisited as a part of tracker #14157
