IMO all namespace names should contain a year, because the association
between a domain and the organization that owns it can vary from year
to year.  "Hackers.com" has been owned by at least four organizations
that I know of.

NewsML URNs, which are perfectly general and can be used even outside
NewsML, are of the form urn:newsml:foo.com:yyyymmdd:uniqueid:1, where
yyyymmdd is any date on which the minter of the URN controlled foo.com.
Some people use the date on which the URN was minted, others use a
fixed date.  (1 is the version number, which must increase though not
necessarily consecutively, so it can be a timestamp.)
