Hi Ron,

The introduction spends its time likening CRH to RH0 and says it differs by “encoded in fewer bytes” and “addresses security vulnerabilities”

I was left with the impression that you are attempting to recreate another general use IPv6 routing header for the internet.  Like RH0.

It's only in section 9 where there is a hint that is not the case, you say “Networks that process the CRH MUST…”.  I could not find a definition of these networks.
