This does, of course, address my concerns, and I withdraw them.  But the
context on my part is probably worth explaining.

Properly, you should use "scheme" here rather than "URI".  "URI" is a
very general universe of identifiers, and "URNs" are a subset of them.
So any "namespace" of URNs is perforce a set of URIs as well.

OK, that was the point that was not clear to me, that the namespace
registration is sponsored by the DOI Foundation.

There was another source of confusion that DOIs as I've seen them
(generally in academic papers and references thereto) are usually
written in a form that *look* like URIs and I reflexively assumed that
DOIs were defined to be compatible with URI syntax, thus allowing "doi"
to be a URI scheme directly -- and that this was intended by the
Foundation.  But IIRC from this discussion, the character set in DOIs is
not limited to the URI character set, so even though all of the ones
I've seen look like URIs, they aren't.
