It will follow any URI for the file, but it must be rel=meta -- not a  
URI at all.

It currently processes it in just the same way as an HTML link element.
This gives the HTML WG control of a bit of HTTP spec, effeciively.

We could argue that   'rel=meta' here is a relative URI relative to a  
common default.

Not in this implemention.

But I must admit thinking of HTTP headers

Prefix: dc=
N3:  <> dc:title "Another interesting picture".

The prefixes would have to affect all the N3: headers, ie be deemed  
to have been given first, as http is unordered.
