How is that information communicated to the world?  Is it documented
somewhere, or expressed in-band?  If not the latter, then I'd say
that's not passable because, from a REST POV it's not respecting the
hypermedia constraint.  I'd suggest returning a Link header using the
"alternate" relation type, e.g.

GET /user/23 HTTP/1.1
Host: example.org
Accept: application/rdf+xml


HTTP/1.1 200 Ok
Content-Type: application/rdf+xml
Link: <http://example.org/user/23.n3>; rel="alternate"; type="text/n3"
Link: <http://example.org/user/23.html>; rel="alternate"; type="text/html"
