RFC 8826 — Not-prepped XML
The not-prepped XML is the RFC XML v3 source for an RFC at the moment in the publication process just before the prep tool was used to expand default values, generate section numbers, resolve cross-references, and embed boilerplate.
It is useful for authors who want to begin a new draft based on the RFC's text, such as when creating a bis-draft, and for tools that process author-facing RFC XML.
