Resource AnnouncementDraftUpdater is used to update the fields of a DiscussionsDraft
that is intended to become an Announcement. AnnouncementDraftUpdater inherits
draft destination and body from TopicDraftUpdater. It contains an
AnnouncementDraftPropertiesUpdater used to update properties that don't apply
to a draft that will be used when the draft is posted as a new Announcement,
such as expiration date.
Below are examples in XML formats. All examples are shown with all inherited members. Quoting when required is part of the examples, but you must obviously populate with your own data.
