(I notice that the URN drafts call these "namespaces" rather than
"schemes", so we will have to be careful to distinguish XML namespaces
from URN namespaces.)

At www.ietf.org, I find the following:

1. http://www.ietf.org/internet-drafts/draft-ietf-urn-nid-req-08.txt

  This document lists the requirements for registering a URN
  namespace.

2. http://www.ietf.org/internet-drafts/draft-ietf-urn-ietf-09.txt

  This document proposes the IETF namespace for RFDs, etc.

3. http://www.ietf.org/internet-drafts/draft-ietf-urn-net-procedures-02.txt

  This document proposes a mechanism for using DNS to obtain
  resolution hints for URNs.

4. http://www.ietf.org/internet-drafts/draft-ietf-urn-dns-rds-00.txt

  More on DNS and URN resolution..

5. http://www.ietf.org/internet-drafts/draft-ietf-urn-naptr-rr-02.txt

  More on DNS and URN resolution.

Am I missing some other documents?  As far as I can see, the only URN
namespace that is proposed in an IETF draft is the IETF namespace, and
I cannot use a URN in the IETF URN namespace to create my own XML
namespace.

Where can I find the IETF draft documents describing URN namespaces
built on DNS, ISBN, UUIDs, etc.?  Perhaps I just haven't looked in the
right place.


Thanks, and all the best,


David
