Is the idea to require a syntax that has a date? dns-urn:netloc/date/doc-id 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.
