For some reason I have not had any problem with URIs as abstract identifiers
myself, but it is obvious from all the questions and arguments on many lists
that the "established practice" argument carries a lot of weight.  So maybe
unrestricted URIs for namespace identifiers should be regarded as a
partially failed experiment.

It would probably have been better if the W3C had said that, if you want to
have a pure identifier that is not intended to give network access to a
resource, then use the w3c-ndi: scheme ("W3C Non-dereferenceable Identifer")
or some such, and to have issued an RFC that specified exactly those

I suppose that too much would break if this were imposed now, but it could
still be phased in as a strongly recommended practice.

Or maybe there would still be a need to have namespaces point directly to
RDDL documents.  Ah, well.
