Thank you for this document.

I have a couple of minor points you can address with any other last call comments.

## Comments

### Terminology

Section 3.2:

> Dictionaries are ordered maps of key-value pairs, where the keys are short textual strings and the values are Items (Section 3.3) or arrays of Items, both of which can be Parameterized (Section 3.1.2).

Just to be consistent, is there a reason why you are not using "Inner Lists" instead of "arrays of Items" here?

### IANA registry

Please make sure to update https://github.com/protocol-registries/http-fields to add the Structured Type field (ah) in the template. Also, should this doc be added to the Reference of the IANA registry itself? (I know the note itself includes a pointer, but it might be good to duplicate there as well).

### Security considerations

Section 6:

> See also [UNICODE-SECURITY] and [I-D.draft-bray-unichars].

What parts of [I-D.draft-bray-unichars] is the reader supposed to look at? Or if it is the whole document, could we have some context around it?
