I'm balloting NOOBJ largely on the basis that the document appears to be of
high quality and would probably be clear and usable if only I had the necessary
grounding in HTTP's more abstruse corners to make sense of it. (Thank you for
the references and examples, those got me halfway there, perhaps. The other
half is the part I'm taking on faith.)

I do have a few nits and questions --


### Section 5, reserved token value

In your description of the Status template field, you have ""reserved" - for
algorithms that use a reserved token value that cannot be expressed in
Structured Fields". This is a well-formed sentence but I have no idea what it
means. I made a desultory attempt to suss it out by searching the document for
"token" and this was the only occurrence. If people who will actually be making
use of the registry can be expected to make sense of it, then feel free to
disregard my comment, of course.

### Section 5, "optionally the key"

A few lines further down you have "Reference(s): pointer(s) to the primary
document(s) defining the technical details of the algorithm, and optionally the
key". I couldn't work out what "the key" is in this context, that would be
placed in the registry. The values you've seeded the registry with don't
provide any examples, so I'm none the wiser for having checked there.


### Section 6.5, e.g.

In "Since it is possible for there to be variation within content coding, the
checksum conveyed by the integrity field cannot be used to provide a proof of
integrity "at rest" unless the whole (e.g., encoded) content is persisted.", do
you actually mean "i.e." and not "e.g."?

### Appendix A, typo

/entires/1234 should be /entries/1234
