So, that implies that all data in the ORIGIN frame might be false.
Doesn't that deserve a bit of a health warning at the beginning of the
Security Considerations? Also, using the word "believes" of a server
is strange. How would the server acquire uncertain knowledge in the
first place, and what algorithm would decide what it "believes"?
Appendix A doesn't show any sign of a client checking whether an
Origin-Entry is real.

In that reference:
>> Literal IPv4 and IPv6 addresses are not permitted in "HostName".
Is that an intended or unintended restriction for the ORIGIN frame?
In any case it should probably be mentioned explicitly to avoid confusion.
(If IPv6 literals were allowed, they might be very convenient for server
load balancing. But RFC6066 excludes that.)
