Reference pages have their own hierarchical structure. A
               RefSect1 is a major division in a
               RefEntry, analagous to a Sect1 elsewhere
               in the document.
               
            
               The value of a separate hierarchical structure is that it allows
               the content model of sections in reference pages to be
               customized differently than the content model of sections
               outside.  For example, because of this split, it was easy to add
               a recursive sectioning element (Section) as a peer
               to Sect1 in DocBook V3.1 without introducing it to
               RefEntrys, in which it would not be desirable.
               
            
Formatted as a displayed block.
In some environments, the name, number, and order of major divisions in a reference page is strictly defined by house style. For example, one style requires that the first major section after the synopsis be the “Description,” which it must have as its title.
                  In those cases, it may be useful to replace RefSect1 in
                  the content model with a set of named sections (following the pattern
                  of RefNameDiv and RefSynopsisDiv).
                  
               
                  Formatting reference pages may require a fairly sophisticated
                  processing system.  Much of the meta-information about a
                  reference page (its name, type, purpose, title, and
                  classification) is stored in wrappers near the beginning of
                  the RefEntry.
                  
               
Common presentational features, such as titles and running headers, may require data from several of these wrappers plus some generated text. Other formatting often requires that these elements be reordered.
The following elements occur in refsect1:
                  abstract, address, anchor, authorblurb, beginpage, bibliolist, blockquote, bridgehead, calloutlist, caution, classsynopsis, cmdsynopsis, constraintdef, constructorsynopsis, destructorsynopsis, epigraph, equation, example, fieldsynopsis, figure, formalpara, funcsynopsis, glosslist, graphic, graphicco, highlights, important, indexterm, informalequation, informalexample, informalfigure, informaltable, itemizedlist, literallayout, mediaobject, mediaobjectco, methodsynopsis, msgset, note, orderedlist, para, procedure, productionset, programlisting, programlistingco, qandaset, refsect1info, refsect2, remark, screen, screenco, screenshot, segmentedlist, sidebar, simpara, simplelist, subtitle, synopsis, table, task, tip, title, titleabbrev, variablelist, warning.
               
                        Status identifies the editorial or publication 
                        status of the RefSect1.
                        
                     
Publication status might be used to control formatting (for example, printing a “draft” watermark on drafts) or processing (perhaps a document with a status of “final” should not include any components that are not final).
