  Silva News objects are a separate product, an extension to Silva
  (that must be installed). The NewsArticle and AgendaItem objects
  only appear within a NewsSource (thus not in a 'normal'
  Silva publication). 

  **News Source** --
    A special Silva publication that offers
    NewsArticles and AgendaItems. The Source can be accessed by
    NewsFilters in other locations within a Silva site.
    <br /><br />

  **NewsArticle** -- 
    A News item that appears as an individual page.
    By adjusting settings the Author can determine which period,
    which subjects, and for which audiences the Article should be
    presented.
    <br /><br />

  **AgendaItem** --
    A News item for events. Includes date and
    location metadata, as well settings for subjects and audiences.
    <br /><br />

  **NewsFilter** --
    To enable editors to channel newsitems on a site,
    all items are passed from NewsSource to NewsViewer through filters.
    On a filter you can choose which NewsSources you want to channel
    items for and filter the items on several criteria (as well as
    individually). Also NewsFilters can be set up to forward their
    items to other systems as an RSS stream (RSS version 0.91).
    <br /><br />

  **AgendaFilter** --
    To enable editors to channel newsitems on a site,
    all items are passed from NewsSource to NewsViewer through filters.
    On a filter you can choose which NewsSources you want to channel
    items for and filter the items on several criteria (as well as
    individually).
    <br /><br />

  **Agenda- &amp; NewsViewer** --
    Used to show news items on a Silva
    site. When setting  up a newsviewer you can choose which news- or
    agendafilters it should use to  retrieve the items, and how far
    back in time it should go. The items will  then be automatically
    fetched via the filter for each page request.
