Summary: Draft is not ready; security analysis is incomplete. Recommends DISCUSS.

Review comments:

I reviewed these documents for IETF LC and they have not been updated since.

I am told that some changes are in the pipeline in the form of RFC 
editor notes but I haven't seen them as yet.

My reviews suggested that these were useful documents but highlighted 
two major areas of concern:
-,Failure to provide security analysis although it is stated that it has 
been done in the security considerations section
- Informal wording that conceals the true problems rather than 
explaining them:  In particular the analysis of the race condition is 
just too informal, has somewhat incorrect conclusions  and needs to be 
modified to make it clear (especially to non-English mother tongue 
readers) what is going on.

It may be that the updates will fix these but they certainly need some work.

I'll send an update if and when the RFC Editor nodes appear, but 
otherwise Brian might like to consider a holding DISCUSS on the lack of 
security analysis.
