Summary: The document is well-written, clear, and to the point. I only found a
few nits with opportunities for clarification.

Major issues: None.

Minor issues:

Section 2:

" Fully-Qualified Domain Name (FQDN): This is often just a clear way
          of saying the same thing as "domain name of a node", as outlined
          above.  However, the term is ambiguous."

These two sentences appear to contradict each other - Is the term clear or
ambiguous? I suggest removing the word "clear" to simply state how the term is
commonly used, and then point out the ambiguity.

Section 3:

"6. server replies with an updated order object […]"

Is this updated order object similar to the "authorization" objects?
When it says "authorizations" in step 2, are these also objects?
I suggest defining the term "object", e.g., in Section 2, and then
double-checking that this term is applied consistency in the document.

Nits/editorial comments:

Section 4.3:

"If the client is unable to fulfill authorizations against parent domain"
-> "If the client is unable to fulfill authorizations against a parent domain"
