No, I was not suggesting that a resource would point to itself as a
source -- it already gives that information to the client via the methods
allowed on itself.  What I was suggesting is that there is no such thing
as a resource type.  Resources simply allow or do not allow methods,
and link to or do not link to other sources.   It is a web.  The job of
the client is to let the author know that this web exists when it
encounters a resource with links to sources.

A redirection.  There is no such thing as a redirected DELETE that doesn't
require user confirmation.  However, if the client accesses a resource
using WebDAV and that resource does not allow DELETE and that resource
does have a source link, then isn't it reasonable for the client to ask
the user if they would really like to delete the source resource instead?
Client implementations can figure that one out for themselves.
