Ooooh, that's a fascinating example!

One can consider a "data:" URI to be a URL, since it provides a way to
locate the referenced information (i.e., parse the URI).  Nonetheless,
it does not contain a DNS name or any other identifier of a network
resource.

And yet it's also a URN, because it is a persistent identifier of the
referenced information -- the association of the URI with the
referenced information never changes!
