Compatibility with GLIF and perfSONAR usage -------------------------------------------
The current syntax is compatible with both current usage, although it is now specified that recipients of a URN SHOULD NOT interpret the local part. This is a change from the existing use.
Also, the document specifies that the following two URNs are NOT lexical equivalent. I have no opinion on this. Should this be equivalent or not? - urn:ogf:network:example.net:path:2011-0418 - urn:ogf:network:domain=example.net:path:2011-0418 I think the "domain=" part is superfluous in the way that we now construct identifiers. In order to reduce cruft and burden the urn with legacy from the start, I say that we make them inequivalent.
International Characters ------------------------
No international characters are allowed. I actually worked out a solid schema (using RFC 5982 and NFKD normalisation that would allow quite a few code points, but still have a very simple URN comparison -- no decoding required.), but decided not to use it.
I have no opinion on this, but the comments on the IETF list make sense.
