date in URN

Is the idea to require a syntax that has a date?
or would it just be part of the OS
	dns-urn:netloc/OS           (where OS = date/doc-id)

Also, would you elaborate on the difficulties with potential reuse of
identifiers and how this solves them. If URNs will have a date in them,
then the RFC should say something about why they are needed.
