Hi adam

I had a brief look and this is a good start. I really think that we 
need this kind of architectural
support to avoid all the hardcoded mess. I have the impression that the 
annotations are not really required we can simply use the class 
initialize way for now as we do it in FileList.

Now could you propose a first version that does not depend on roel and 
andreas stuff.
Then as avi mentioned it would be good to create a simple object like 
in the registration mechanism of the FileList. These kinds of changes 
are also really important because people tend to copy what they see and 
we could also have more behavior on them.

I'm a bit relunctant with annotations because I see more and more ugly 
stuff in VW like the delegate that vassili presented at ESUG. If we 
want that we can do it at the language level not at annotation level. 
Note that I'm reserved about annotation but this does not mean that I'm 
against new features  in the language but I study a lot languages and I 
would appreciate that we do it well :)

So to summarise can you produce a changeset with resgistry and items so 
that we can evaluate what is the best way to push that in the image.
