metanorma-ietf lets you write IETF documents, such as Internet-Drafts and RFCs, in native AsciiDoc syntax. This is part of the Metanorma publishing framework. RFC XML ("xml2rfc" Vocabulary XML, RFC 7991) is the XML-based language used for writing Internet-Drafts and RFCs, but not everyone likes hand-crafting XML, especially when the focus should be on the content. This gem is in active development. Formerly known as asciidoctor-ietf.
