I think what Peter was talking about is an editing interface where
specialized editors can hook in, and that provides a general default
editor where the specialization is not needed. 

Something you feed a DOM node in and get e.g. a JComponent out. You can
register your own constructors for elements, and if you don't, you get a
default
JComponent. 

something like

class DOMEditorFactory {
  registerElementEditor (Sring namespace, String name, Class
editorClass);
  JComponent createEditor (Node node);
}

The registered class would be required to implement a constructor
that takes a pointer back to the factory and a DOM element as input. 
An editor for a node can ask the factory for editors of it's
childs when it is expanded. 

If context-dependent or non-default editors for other than element nodes 
are required, the parent element needs to build the corresponding
component itself. Another possibility would be subclassing the
factory and overwriting createEditor.
