Except (and this is a very important except), this has application outside
the context of HTTP and other document transmission schemes. For
example, if documents are stored on a network (an Intranet without a
dedicated server), or on CD, or even on an FTP server then HTTP
content negotiation is of no help. The functionality should be handled at
the HTML or the URN level. (And should be integrated with HTTP content
negotiation where appropriate.)

I agree that alternate document sources should either be enabled via a
very simple extension to the appropriate tags (HREF, IMG, OBJECT, ...) or
via a more comprehensive solution using LINK as Dan suggested.
However I can't think of any forum more appropriate than this one.
