Summary: This document was clear and well-written. I found no issues and noted some number of small nits below.

Major issues: None

Minor issues: None

Nits/editorial comments:

In s1.2 (Notational Conventions), I didn't understand what greedy meant in:
   In some places, the algorithms are "greedy" with
   whitespace, but this should not affect conformance.

In s2 (Defining New Structured Fields), perhaps "Reference this specification."
  should instead be "Normatively reference this specification." ?

In s2, the definition of Foo-Example Header seems to be enclosed in
  "--8<--" and "-->8--" in the TXT version, could be a bug in the tools?

In s3.1.2 and s3.2, in the example, I was confused by "a=?0" and "b=?0" until I s3.3.6.
    Perhaps reordering sections or adding a reference would help?

Should there be some guidance for defining new integer fields that don't fit in 10^15?
    Is a String the recommended approach?
