[media-types] Multipart without boundaries

[Rahul Gupta <[e-mail]>]

Hello Media-type enthusiasts,

I am proposing a new Internet-Draft "Multipart without Boundaries".
https://cxres.github.io/multipart-without-boundaries/draft-gupta-mediaman-multipart-without-boundaries.html

Like the title says, it proposes a new syntax that uses `Content-Length` in each part and thus does not use boundary delimiter to separate encapsulated parts. As explained in the draft, this solves an outstanding issue when parts are dynamically generated (and generally simplifies parsing), especially when used in notification protocols (It is inspired from Braid's subscription response, but respects existing HTTP content-type conventions).

One issue that I faced while writing this draft is that I could not find a IANA registration for the "boundary" parameter for "multipart" media-type in any of the registries. So I am not sure of what instructions to give to IANA for the "no-boundary" parameter.

This is a tiny draft that solves a very specific and limited issue. I know that I am too late for I-D submission and publishing it almost on the eve of the Brisbane round, but I would still appreciate it if the Chair could please sneak it in at least as an announcement (or 5 minute discussion) in the Mediaman session.

Thanks in advance,

Best Regards,
Rahul
