This read-create RowStatus object manages the creation and deletion of entries in the Announcement table, noting that once a row is created it cannot be modified, only destroyed. An admin uses this to add a new permanent announcement entry, which requires cwAnnFileName to be set, or to remove an existing one by setting this object to destroy, since in-place edits aren't supported. For example, to change an announcement file associated with an existing entry, the admin would have to destroy the old row via this object and create an entirely new one, rather than modifying it directly.
