         This extension point is used to define a special viewer capable to present change objects. The reader of 
         the extension point provides the following predefined variables which can be accessed during 
         expression evaluation using the &amp;lt;with variable=&quot;...&quot;/&amp;gt; tag: 
&lt;p&gt;
&lt;dl&gt;
  &lt;dt&gt;change&lt;/dt&gt;
  &lt;dd&gt;the change object to present a preview for&lt;/dd&gt;
&lt;/dl&gt;
&lt;/p&gt;
The default variable used during expression evaluation is bound to the change variable.
