This would mean that if you wanted to change the accompanying effects
you would have to change all pointers.  Perhaps what we really need is
URLs that point to a group of files which should be fetched and
presented simultaneously (a "compound node" in the terminology of the
Dexter hypertext reference model).  I don't know enough about HTTP,
but possibly a variant of Content-type: multipart could be used here?
