1//! IETF RFC XML (v3) format implementation
2//!
3//! # Status: Experimental
4//!
5//! This is a parse-only proof-of-concept import for IETF RFC XML (v3)
6//! documents. It is kept in-tree because it's a useful demo of
7//! Lex-as-target, not because it is a release-quality format. The
8//! project invests **no bespoke time** here — only improvements that
9//! fall out of IR-symmetry work for free.
10//!
11//! Do not invest engineering effort in this format unless the v1
12//! interop bar (Markdown round-trip, HTML/PDF export) is already
13//! solid. See the full tiering at `comms/docs/interop-scope.lex`
14//! in-repo, or
15//! <https://github.com/lex-fmt/comms/blob/main/docs/interop-scope.lex>
16//! on the web.
