I am not sure I understand you correctly. Basically, the goal is to keep 
as many URIs as possible relative, so rewriting them to absolute URIs is 
a Bad Thing (TM) IMHO.

Also, it is not clear how the rewriting should work. For example:

source element: <a href="../foo/bar.xhtml">Bar</a>

How should this be handled? Simply prepending the domain part of the 
edited document base URI would result in <a 
href=http://www.example.com/../foo/bar.xhtml">Bar</a>.

We could of course simply prepend the the URI of the edited document 
minus the document name itself, e.g. <a 
href="http://www.example.com/some/documents/../foo/bar.xhtml>Bar</a>.

But, as I've said above, this is generally not what you want, because 
you can't guarantee that the rewritten link is actually valid (ok, you 
can never guarantee that, rewriting or not), and coercing relative URIs 
to absolute URIs is not a good idea.

Also, there's the question of how to integrate that into the UI. If you 
have a good suggestion on how to do it, I would be glad to hear it! :)
