The advantage is that existing catalogs, either actual 9401 socats, or translated versions thereof, contain mappings and delegations for public ids. If we give a document a public id, we can refer to it uniformly via the public id, even where we need to tunnel the public id as an URN. The alternative is to have ugly duplications, saying: "Map -//W3C//DTD Foo//EN to http://www.w3.org/foo" "Map urn:publicid:-:W3C:DTD+Foo:EN to http://www.w3.org.foo" which can easily drift out of sync. To my mind, the public id and its URN-encoded equivalent are exactly the same name, and ought to be addressed by a single set of catalog entries. -- There is / one art || John Cowan <jcowan@reutershealth.com> no more / no less || http://www.reutershealth.com to do / all things || http://www.ccil.org/~cowan with art- / lessness \\ -- Piet Hein
