Well, but remember the price of making these the same
in XLink.  XLink systems can't answer a simple
question like "Do you and I link to the same resource?"
We might, but if we specify it using distinct names,
as above, we aren't going to know except by trying.
In RDF, the answer is simple to find and does not
require actually fetching the resource.
