Each page change item is a PageChangeItem object, which stores information describing a page change, such as: EndTime--RTC time of the last stroke (for an AFD) or last data saved (for a penlet), PageAddress (page address), Page (page number). 

The Pages property will be empty if the package described in the ChangeItem is a penlet.
