New issue: Header type for JWT format values

I posted this a few hours ago, but it hasn't shown up in the archives
<https://lists.w3.org/Archives/Public/ietf-http-wg/2025JulSep/> yet, so
posting again:

Hello,
We are currently working on a draft for Transaction Tokens
<https://datatracker.ietf.org/doc/draft-ietf-oauth-transaction-tokens/>,
which envisions a new HTTP Request Header called "Txn-Token"
<https://www.ietf.org/archive/id/draft-ietf-oauth-transaction-tokens-05.html#name-txn-token-http-header>.
The header value is expected to be a JWT.

We were debating (see comments here
<https://github.com/oauth-wg/oauth-transaction-tokens/pull/176> and the
attached screenshot) which HTTP Structured Header Type
<https://www.rfc-editor.org/rfc/rfc8941.html> would be appropriate for such
a value. We do not want to enclose the value in quotes, so the STRING type
cannot be used. The JWTs also might be a bit long (> 1024 bytes).

What is this group's guidance for proposals that want to add HTTP Headers
that have JWT as their values?

Thanks,
Atul

trying without the screenshot.
