@ianswett thanks for the new text, that helped.

I think we've resolved outstanding issues, unless my new text has created new problems.

2 possible ways to enlarge this solution:
- should we describe this attack in Security Considerations? As these MAYs are an effort to counter something in particular, perhaps we should discuss.
- it would clean up some accounting issues if each NCID frame MUST set Retire Prior To to more than the maximum continuous sequence number that it had recieved an RCID for. Worthwhile?
