+Properties appear in the user interface in three contexts:
 in indices, in editors, and as filters.  For each type of
 property, there are several display possibilities.  For example,
 in an index view, a string property may just be printed as
 a plain string, but in an editor view, that property should
 be displayed in an editable field.
 
-<p>The display of a property is handled by functions in
-a <tt>displayers</tt> module.  Each function accepts at
-least three standard arguments -- the database, class name,
-and node id -- and returns a chunk of HTML.

+<p>
+Displayer functions are triggered by <tt>&lt;display&gt;</tt>
 tags in templates.  The <tt>call</tt> attribute of the tag
 provides a Python expression for calling the displayer
 function.  The three standard arguments are inserted in
 front of the arguments given.  For example, the occurrence of
 
 <blockquote><pre><small
->    &lt;display call="plain('status', max=30)"&gt;
+>    &lt;display call="plain('status')"&gt;
 </small></pre></blockquote>
 
-in a template triggers a call to
-    
-<blockquote><pre><small
->    plain(db, "issue", 13, "status", max=30)
-</small></pre></blockquote>
-
-when displaying item 13 in the "issue" class.  The displayer
+in a template triggers a call the "plain" function. The displayer
 functions can accept extra arguments to further specify
 details about the widgets that should be generated.  By defining new
 displayer functions, the user interface can be highly customized.
 
-<p>Some of the standard displayer functions include:

 <p>An index view contains two sections: a filter section
 and an index section.
 The filter section provides some widgets for selecting
 which items appear in the index.  The index section is
 a table of items.
