    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 earlier v3 grammar described in RFC 7991, which in turn obsoleted the v2 grammar in RFC 7749.},
