    abstract =  {This document defines the "xml2rfc" version 3 vocabulary: an XML- based language used for writing RFCs and Internet-Drafts. It is heavily derived from the version 2 vocabulary that is also under discussion. This document obsoletes the v2 grammar described in RFC 2629 and its followup, RFC 7749. Editorial Note (To be removed by RFC Editor) Discussion of this draft takes place on the rfc-interest mailing list (rfc-interest@rfc-editor.org), which has its home page at \textless{}https://www.rfc-editor.org/mailman/listinfo/rfc-interest\textgreater{}.},
