Re: URN namespace

Any naming system that uses current DNS domains and expects long term
persistence also requires at least a low-frequency time stamp, because
current DNS domains are not guaranteed long term persistence.

I think 'year' is good enough, but 'year and month' might be better.

Note punctuation elided. If year=currentyear, use DNS, otherwise use
some other service.

I think the key element isn't 'ease of creating' but 'frequency of
reassignment'. We should all have heard of the cases of 'mtv.com' and
'kaplan.com' and 'bbb.com' already, right?
