Summary:

This draft is basically ready for publication, but has nits that should 
be fixed before publication.

ISSUES: 0
NITS: 2

1) NIT: Lack of normative language for syntax

I gather this document intends to normatively specify some of the syntax 
of HTTP requests and responses. Yet the specification fails to use 
normative language. For instance, consider the following sentence from 
section 2:

"The Cache-Groups HTTP Response Header is a List of Strings 
[STRUCTURED-FIELDS]."

To clearly be normative, I would expect this to be stated as:

"The Cache-Groups HTTP Response Header MUST be a List of Strings 
[STRUCTURED-FIELDS]."

This problem is present in sections 2 and 3, and also in the reference 
[STRUCTURED-FIELDS].

2) NIT: Typo

In section 2.1:

s/The both/They both/
