 * replace a specific child component with a new component having the same id 
(with method _replace_).
-* iterate thought children components with the iterator returned by method 
_iterator_ or using visitor pattern with methods _visitChildren_.
+* iterate thought children components. This can be done in the old way 
(pre-Wicket 8) using method _iterator_ or using visitor pattern with method 
_visitChildren_. Starting from Wicket 8 the same task can be accomplished using 
the _stream_ object returned by methods _stream_ (which contains only the 
direct children) and _streamChildren_ (which contains all children).
 
 Both _Panel_ and _WebPage_ have their own associated markup file which is used 
to render the corresponding component. If such file is not provided, Wicket 
will apply markup inheritance looking for a markup file through their ancestor 
classes. When a panel is attached to a container, the content of its markup 
file is inserted into its related tag.
