IETF Gurus,
I'm looking for a URN scheme that uses DNS for uniqueness (perhaps in
conjunction with a date) but doesn't have any attached semantics. I'm
asking this beacuse XML has the duck problem. It uses URIs for
namespace names, but only the URI syntax (for uniqueness), thus you see

ick. please don't embed URIs in URNs. that will just tempt people
to use the embedded URIs and not treat them as URNs.
I can see wanting to have a URN that's based on DNS, but there shouldn't
be any expectation that you can derive a URI from the URN just by
modifying the syntax. that defeats

I'm not set at all on using URIsh syntax. I just thought
it'd be the easiest approach.

It's good enough.
OK...
- it uses DNS to gaurentee uniqueness
The DNS does not guarantee uniqueness outside of a TTL;
you need a timestamp to accomplish this.
- next is a domain name in *small caps*
Do you mean lower-cased?
- a standard httpish path per URI specification.
There are a lot of does this
