Summary:
This document specifies a new "challenges" for Automated Certificate Management
Environment

Major issues:

Minor issues:

Nits/editorial comments:
The 3rd paragraph of the Introduction stated that this New Challenges requires
negotiating a new application layer protocol, but no existing software
implements this protocol. Therefore the ability to fulfill this challenges is
effectively "opt-in". I find the statement is quite confusing. Does it mean
that it is necessary to manually add processing to handle the challenge because
 there is no implementation of auto negotiation?

Thanks,
Linda Dunbar
